Not on MY team. I think he may stick, but with a one year window for the Warriors to take a decent run, I wouldn't go that way. He can play a ton in AAA and come back next year. No 16 year old should play in the league unless they are a LOCK (IMO) and, although White has been good-- he'll be a player in the future-- he's not as valuable to the Warriors this season as a 19 year old vet is.
That said... I like Hansen, Eberle and DeRoose much better-- as far as keeping young guys around.
