Callahan had beat OEL to the puck, OEL grabbed his arm, while they were crashing into the board. OEL was the one who caused this injury. If he does not grab Cally's arm they both go into the boards and take minimal damage. I mean a 4-1 game and he is still hustling for the puck. It's like blocking shots during pre-season. I love the effort but sometimes have to save it for the right moments. That was not one of them, having a 3 goal lead, against a garbage crap team who will likely be sold or relocated. But I think he really wanted a goal so bad, he was hustling to make a play.
As per his play, he has been great. He is not getting PP time, and does not get the top 6 mins. So when he has games with 5 SOG, that is impressive for a guy not in the Top 6. They were some high quality chances also. Refs yet again screwed him. Yeah, I know it's petty to bring up all the times he was denied a goal or points taken away by the refs this season, but in his role, every little point counts or is important since they don't just land on his lap or gets them on a PP and whatnot.
