the only reason he went undrafted was because of his injury. You can't tell me from watching college ball that a Healthy Seth Curry can't be effective in the NBA. I think he will be more effective than some first round players. Obviously going to the warriors he won't get much playing time but he could be a secret weapon come playoff time.
I can tell you that with ease. What's the difference between Seth and say, Jimmer Fredette? Jimmer is a much better shooter, maybe a slightly better athlete and a lot more durable. Jimmer's days in the NBA are marked b/c he can't get produce for the lowly Kings. The only reason Seth is getting a look is b/c of his surname.
