Nobody can convince me he doesn't have a serious injury to his wrist. Something he can play through but if it doesn't ever get to 100% he will not be that same deadly sniper. 40 Goals a year is still great, especially with his defense and stick work; but I just see a different shot from him.
Last night for instance, the old Matthews scores a minimum of two goals from those looks. I'm not taking anything away from Bob but the Matthews of a year or two ago buries those looks with his deceptive sniper of a shot.
As long as the Leafs win and he is out there competing, so often dominating and winning, he will be the leader this team needs in the crunch. You hear many players talk about how hard he works and he constantly wants to improve. His defense has only improved which allows his line to compete against even the best defensive lineups 5v5.
That said, in his very first game in the NHL, when he did the insane and scored 4 goals, all of them were in close. So, instinctively, he has always used a good stick and scored in tight.
Perhaps last year he went overboard in his pursuit of 70 and injured his wrist or something I don't know.
