I follow the Winterhawks and I've got family who are STH in Montreal. I hear way more than I want to, in excruciating detail, about any slug who's pulled on a Habs uniform -- especially when he used to play for a hated rival.
So you didn't like him on the Winterhawks then? What deficiencies did you see in his game when he led them in defensive scoring his final two years? That team had the best regular season record in the WHL & Morrow was the WHL's 1st team all star. I doubt any Winterhawks fans were complaining about him.
Everything I've read about him thus far begins with an outstanding training camp in his draft year in Pittsburgh. He almost made the team & was their final cut, being sent back to junior where he had the season I just described.
Knee injuries apparently play a role in his development in junior, but throughout his pro career there's been none. Hard to get injured when not on the ice. He's been a healthy scratch 2/3'rds of his NHL career & that's a recipe for disaster with a young player. His lone time lost to injury was an extreme case of the flu.
NHL scouts viewed him very highly until recently. He's been traded multiple times but examining the trades in context show that he's been traded for some rather decent players.
Krug, Chara & Seidenberg all naturally played ahead of him at LD in Boston so he became a fixture in the press box. The games he did get in often had him play as the 6th defensemen on his off side at RD.
He remained a press box filler in Montreal which brought him to Winnipeg for a 4th rounder.
