Well, I won't weigh in on his upside yet, since we've yet to see him play a preseason game, let along a regular season one. However, I do think it'll be interesting to see what effect he has on Baby over the year.
If Luke plays well (and to some extent if Perk recovers well), we could see Baby traded at the deadline. Not only could Baby be a valuable chip as the playoffs approach, you also have to wonder how much Danny is willing to spend to keep Baby around.
I like him, I really do. But I don't think he's a big enough part of the future to justify giving him a big new contract.
