Tinordi 22nd OV 2010 and Nathan Beaulieu 17th OV 2011, in the case of Dmen most of them take 4 yrs. before breaking into protected icetime use in the NHL. An extra season playing for the Calder Trophy surely can't hurt their development, another year to mature playing in arguably the next best hockey league outside the NHL. As to the coaching of the rookies, the Parity of teams in the NHL being close to the level of the Original Six, makes it difficult when playing the Elite teams. Players deficiencies are exposed as Beaulieu was by the play of Bennett of Pittsburgh. Great forwards will undress offensive defencemen, making cutesy plays that work in the AHL quite often. Pete Mahovlich said before that game how Bennett's play was so outstanding in the AHL, he had nothing too learn there.
A year vying for the Calder Cup and a long playoff run should be sufficient in preparing these two Dmen for next season, perhaps earlier if they simplify their game. Experience is the necessary ingredient for both,IMHO. Not that I'm any kind of expert, but like most hockey people say, playing in the AHL has never hurt any player. I believe in that theory, the Habs defence will be better for having veteran Dmen like Gonchar, Allen, Weaver and Gilbert. When injuries occur, our AHL dmen will be game ready to step up and have more hockey knowledge to glean from these veterans.
