I posted on Twitter about speculated BU departures, mostly sophomores. I dont follow the East too much, but my feeling is if you aren't averaging a least a point a game in college playing teams like Sacred Heart and Massachusetts, you have no business looking to jump to the NHL.
The other thing is, unless you are a player like Jack Eichel, what is the point of jumping to the pros if you are going to spend a lot of time riding buses in the AHL or ECHL? Look at Kyle Turris. He played one year at Wisconsin, jumped, and ended up spending years in the minors. Kyle Connor has been playing in the AHL this year. Most of the players who leave early never go anywhere. For every Jonathan Toews, TJ Oshie, Tyler Bozek, there are mostly players who end up in the minors. Look at this list from last year; how many are playing on NHL rosters? There's Jake Guentzel. Fasching and Nelson have bounced around most of this season, even if they are currently with Buffalo. LaDue has made it with LA the last couple of months. Denver's Moore and Heinen are both in the AHL right now; I shudder to think how good Denver would be if those two had stayed. Guentzel and Schmaltz are the only two on that list I see who have played regularly in the NHL this season.
