Rust will be turning pro after this season. I have no proof, but I would not be surprised to see Wilson and Archibald turn pro this offseason as well.
As far as the sophomores and freshemen, I would wait a couple more years.
If you have no proof, what makes you think he will? Just curious is all, I mean to me, a kid leaves the College rank when he feels his game is at a level where playing there seems redundant and that he should be playing against better competition and the team feels he could benefit from it.
Rust was a long shot up until last season, for him to be in the talks to be leaving soon, admittedly by you with no proof, would be pretty interesting.
I am ok with Archibald and Wilson staying where they are, if they were to move on to the AHL, maybe Shero would finally see what his drafting has accomplished and could move some of the comfortable wingers he's kept around in Dupuis, etc and finally start using some developed talent. Wishful thinking, but I like to stay on the positive side of this.
