Anything can happen.
The QB class, for all intensive purposes, is a little more stacked this year (if they all declare). If there were less 1st round graded QBs, i could see a flurry of trades.
I think it's moot because I can't see the Giants not taking a QB. Eli will be 38 before next season ends, and they won't be planning on picking this high in this good a class again any time soon. If I'm Gettleman and I've got the #2 or #3 pick, the only decision I'm probably making is which QB I like best in this class
