The reason greenway was there was he was transferring schools.I'd write him off. I don't think he gets a contract, and his rights expire in 2 years (so he needs to be really good with Maine to earn an ELC). The only successful player I can think of who played there at 20, who was a late-emerging prospect. Not someone like Greenway who was part of elite programs throughout most of his life. Someone who has an NHL future playing in the USHL at 20, should be the most dominate player in the league by a good margin.
edit: and the only reason Montour was there, was he was waiting to be cleared by the NCAA to be allowed to play at UMass-Amherst, where he dominated in the 2nd half of the season once he was cleared.
I get that at 20 in the USHL is not a good thing, but he when to play while waiting to transfer schools. It's not like he started there and was still there at 20.
Big bodied players sometimes take more time. I'm good waiting to see how these next 2 years unfold is all.
