Got a question on rule clarification, comments on rule enforcements or some memorable NHL stories? Kerry wants to answer your emails at cmonref@tsn.ca. Dear Kerry, On Thursday night in the Chicago/Detroit game, linesman Steve Barton was forced to leave the game due to an injury. I´ve got two questions regarding this situation: 1. Are there any common rules how referees and linesmen split their responsibilities after such a situation happened?2. How many referees (linesmen) is "enough" to finish the game? Is it possible to finish the game with only one referee (linesman) left? (e.g. hypothetically three referees are forced to leave the game) Looking forward to your answers. With best wishes from Slovakia,Peter Bartisek Hi Peter: Cmon Ref is pleased to receive your question from the beautiful country of Slovakia and with the International Games of the Winter Olympics soon to begin. Thank you for your concern for linesman Steve Barton when he was forced to leave the game in Chicago with an injury. Barts is an outstanding linesman and truly one of the great guys on staff. It appears he may have sustained a slight concussion from a hit to the head sustained on Monday night in Phoenix. We wish Steve a full and speedy recovery. Rule 32.6 provides general provisions when a linesman is unable to continue; "Should a Linesman appointed be unable to act at the last minute or through sickness or accident be unable to finish the game, the Referees shall have the power to appoint another in his stead, if they deem it necessary, or if required to do so by the Manager or Coach of either of the competing teams. If no replacement Linesman is available, the two Referees will assist the remaining Linesman with his duties while still retaining their ability to assess penalties when deemed appropriate." In the practical application the two Referees assist the remaining linesman with his duties. The Linesman conducts all end zone face-offs and the lead referee (backing up in advance of the play) picks up the first offside call at the lead blue line and also will make the call on the new hybrid icing rule either by waving the play good or blowing his whistle when he determines icing has been committed. The "Junior" referee conducts neutral zone face-offs. He would most likely assist the Linesman in breaking up fights as well; although it might be agreed upon that the larger of the two referees would perform this physical duty! In the event that three officials were forced to leave the game or were perhaps unable to arrive at the rink due to weather or unforeseen circumstance the authority to appoint replacements is spelled out in rule 31.11. "If, owing to illness or accident, one of the Referees is unable to continue to officiate, the remaining Referee shall perform the duties of the ill or injured Referee during the balance of the game. In the event that a member of the Leagues Hockey Operations or Officiating departments is in attendance at a game where a spare official is present, he shall have the authority to substitute the injured Referee with a spare. If through misadventure or sickness, he Referees and Linesmen appointed are prevented from appearing, the League will make every attempt to find suitable replacement officials, otherwise, the Managers or Coaches of the two Clubs shall agree on Referee(s) and Linesman(men). If they are unable to agree, they shall appoint a player from each side who shall act as Referee and Linesman; the player of the home Club acting as Referee and the player of the visiting Club as linesman." Members of the off-ice crew are typically high level amateur or minor professional hockey officials and could be appointed to act as substitute referees and linesmen if necessary. We have seen situations where this has happened in the past. Peter in Slovakia and all the rest of your fans wish you a speedy recovery Barts.

The 90-plus minutes of play are about trends and approach.Im going to write in defence of Capitals RW Alex Ovechkin, if only because there have been some recent attacks and, while I can certainly live with them being directed at Ovechkin, the analytical process ought to be better, particularly if its going to be a hit piece on the leagues leading goal-scorer. Yes, Im writing to defend a player that is on pace for a 59-goal season, when the second-best goal-scorer in the NHL this season, Torontos Phil Kessel, is on pace for 43. Naturally, I didnt think that Ovechkin would be a player that needed much defending, but hes taken some hits lately. Im going to largely ignore his contributions on the power play because its not in any dispute that Ovechkin is great with the man advantage and can make a difference even when he doesnt score. On one side of the discussion, we have the Toronto Star, with their Department of Hockey Analytics, and while there are plenty of flaws in Ovechkins game, they somehow determined that his goals-for/against percentage was the way to illustrate the problem. Never mind that goals for/against percentage is essentially measuring plus-minus. Ill get to that in a moment but, first, also peruse the Hockey News piece by Ken Campbell who, after Ovechkin was minus-5 against Columbus, decided that Ovechkin has to decide what kind of player he is. After all, Ovechkin was minus-17 on the season after that game. Whats odd about using plus-minus to denigrate Ovechkins contributions is that anyone doing serious analytical work in hockey has been against using plus-minus because it involves so many factors beyond an individual players control (not least of which are the contributions of nine other skaters and two goaltenders when the game is 5-on-5) and, generally, involves small samples because goals are relatively rare events. Its funny to find myself in this position, because I can be a bit of an apologist for plus-minus. You spend enough time around the game and that thinking can be pretty common, and when the sample is large enough, you can get a pretty decent list of players at both ends of the spectrum. (For example, heres the list of players with the best cumulative plus-minus since 2000, and here are the worst.) But, Ive at least learned that there are many other factors that go into whether a player is a plus or minus player, and they must be considered if youre going to attempt to pass judgment on a single season or, especially, a portion of a season. So, lets take a look at some factors that are at play to make Alex Ovechkin a minus-17. First off, the shooting percentage of others on the ice with Ovechkin at 5-on-5 is ridiculously low. His 6.3% is only ahead of fourth-liners Aaron Volpatti and Jay Beagle among Capitals forwards. The suggestion could be made -- and of course it has been -- that Ovechkin isnt making those around him better, but here are the 5-on-5 on-ice shooting percentages when Ovechkin has been on the ice for the past five seasons: 10.36%, 8.62%, 8.05%, 11.76%, 9.09%. Youre really going to have to dig for reasons, other than poor luck and ineffective shooters, to explain even-strength shooting effectiveness declining by 40% over last season, especially when Ovechkin himself is shooting 10.6% (18 goals, 170 shots) at 5-on-5. Taking away Ovechkins 18 goals on 170 shots, leaves the other Capitals to score eight goals on 242 shots (3.3%) with Ovechkin on the ice. Marcus Johansson, his most common left winger, has one goal on 51 shots. This undeniably effects plus-miinus, right? Of course it does.dddddddddddd Give Ovechkin an average on-ice shooting percentage (say, 8%) and that is a difference of about seven goals. At the other end of the rink, Ovechkin is getting burned with a .909 save percentage at 5-on-5. Naturally, the argument will be that Ovechkins defensive play is what leads to that low percentage. Keep in mind, that percentage is well below career norms for him (.922 over the past five seasons, including this one) and ranks near the bottom on the Capitals roster. Use that typical save percentage, on 439 shots against, and that becomes a difference of 5-6 goals. So, why not take a look at where the shots are coming from with Ovechkin on the ice? According to Some Kind of Ninjas Shot Tracker, shots against the Capitals with Ovechkin on the ice at even strength, come from an average distance of 34.5 feet. In the previous five seasons, it has been 34.2, 36.6, 35.8, 34.6 and 35.9 feet on average. There can be an argument made, based on those average shot distances, that Ovechkins most effective defensive performances were in 2010-2011 and 2011-2012 (the Dale Hunter season), but there really isnt a huge difference; goaltenders arent suddenly flummoxed by 34-foot shots when 36-footers are easy pickings. On top of that, best of luck trying to identify those particular seasons as anything close to Ovechkins best. Why? Because he scored 70 goals and 150 points in 157 games over those two seasons, producing the two lowest point scoring rates of his career. Yes, even lower than this season, when virtually no one else puts the puck in the net with him on the ice. Of course Ovechkin is not a defensive whiz, but that shouldnt stand as an indictment any more than it has for elite offensive players throughout the history of the game. Seriously, take a look at the Top 10 goal-scorers in the league, none of whom put the puck in the net like Ovechkin, and identify the ones that are notably strong backcheckers. Some are: Joe Pavelski, Alexander Steen, Patrick Sharp, but theres no reason to believe that right wingers Kessel or Corey Perry or Patrick Kane are doing brilliant work in the defensive end. Heres the thing: theyre all great players! Part of the trouble for Ovechkin is that the Capitals havent been able to win in the postseason, so he gets painted with the brush of failure for a whole host of team shortcomings. Thats what comes with being a superstar. This Capitals team is flawed. They rank in the bottom third of the league in Fenwick Close (measuring shot attempts, not including blocks, at even strength, with the score close), which is a good indication of team puck possession, yet Ovechkin has relatively solid possession numbers. If you want to break down a players overall contribution, and feel that you must use one statistic in order to do so (better yet, dont), then at least reduce the impact of others on the ice and look at the possession stats, because it wont matter that linemates arent finishing or that, for whatever reason, goaltenders arent stopping the puck. Shooting and save percentages fluctuate and while they affect perception -- just ask Tyler Bozak -- they dont get to the bottom of a players on-ice contribution, and so it is with Ovechkin this year, who is having a fine season, no matter what his plus-minus says.
