I agree that Oshie, Chorney, and Finley are gone after this year. And if VV or Kozek really light it up, one of them could sign too. But a part of me thinks that there is a chance that Duncan comes back for his Senior year. It probably won't happen, but of those players above, he is the most likely to stay I would say.
Of these 19 forwards:
Ryan Martens
Andrew Kozek
Darcy Zajac
Brad Miller
Brent Davidson
Michael Forney
Evan Trupp
Matt Watkins
Matt Frattin
Brad Malone
Chris VandeVelde
Brett Bruneteau
Mike Cichy
Brett Hextall
Mario Lamoureux
David Toews
Jason Gregoire
T.J. Oshie
Ryan Duncan
With Oshie gone for sure, that brings us to 18. Wow. Pick 6 from the list above to sit each night. That's crazy. Even if Duncan leaves, I think we could still see some player shifting...maybe Davidson not on the team or Forney going to the USHL for a year or something like Fylling did. Hard to say. There is definitely going to be some competition for playing time at forward!
