Completely unsubstantiated rumours about Hall and character issues have come out for years. I only saw a couple occasions on the ice where Hall didn't act like a complete class act leader. They revolved around yakupov and I'll end it there.
No one, including reporters, knows exactly what happens in the locker room and beyond. I'm of the opinion that Hall matured a lot over his time, but he was always a guy who wants to win over all else.
A funny Taylor Hall story was in about 2011 we pulled the goalie down two with a few minutes left. Other team gets the puck and it's Hall playing goalie against a guy at the top of the slot. Buddy wires one top corner, Hall on his knees attempts to save it with his face. Fortunately he fails, we go down 3 and then Hall goes to the bench livid, to me he was saying wtf did you pull the goalie for, but maybe mad he didn't stop it. Either way, he didn't bail and wanted to win so bad he put himself in whatever opportunity he could to help his team. It might be his greatest strength and biggest flaw. But you got yourselves a warrior.
Now please tell more about larsson, reading the Devils board has made me much more optimistic about the trade than I otherwise might have been.
