What do any of us who don't see practice every day know about any of this. But as fans, we are entitled to have some opinions. I'm not a big Halpern fan. Plays hard, but not enough skill, in my opinion, to be on the top line. If he is in, he should be on the energy line. Likewise, if Helfrich is in the lineup, I believe he needs to be skating on one of the top two lines where you can use his offensive skills. The same goes for Cullen. If they are not getting it done offensively enough to warrant a spot on one of the top two lines, then Appert is right to sit them.
I agree that the two late mistakes that gave Dartmouth the chance to win the game are unsettling this late in the season. I think that you also have to lay some blame at the feet of Jerry D'Amigo for taking a major penalty in the third period of a one-goal game. RPI lost one of its top players and Dartmouth gains some momentum and a chance to wear down the remaining guys late in the weekend.
