I really think this team has a one-year window to make the Frozen Four in 2015-16, and I could see another drop off after that, pending this summer.
Yes, Larkin, Werenski, Compher and Copp are the top prospects. I think a lot of the key players will return, but there is usually a surprise or two. Werenski and Kyle Connor's status could be impacted by which team drafts them, and could recommend the major junior option too.
What style of play does Kyle Connor have? Would like to see him and Larkin paired together next year.
15-16 could have the following:
Sr. class of Copp, Selman, Nieves and Racine
Turning pro candidates of Larkin, Werenski, Compher, Downing and who knows how Connor will play in year 1.
The 16-17 team could be thin with top line scorers and the continued ? in goal.
