Yakemchuk is the most interesting omission imo. One would think they would at least invite him to camp to throw a bone to the long-suffering Sens fans, who if nothing else would enjoy seeing their top prospect play on home ice.
To me, Parekh was a binary choice. Either he's in, as a core part of the team, or he's out. Turns out its the latter. Remember that he was suspended last year for spitting at/on another player. Perhaps questions about his character were the deciding factor there.
Misa and Sennecke are fairly inexcusable imho. I'm a 67s fan and watch Pinelli play most games, and he's in a lower tier of player than both of the omitted players. What Pinelli does have is a lot of bite to his game for a smaller player (and one helluva shot), which may be an indication of where Canada is heading with some of the depth pieces.
