You have 5 teams looking to draft a QB in the 1st/early 2nd round: Houston, Jacksonville, Cleveland, Oakland, Minnesota.
There are 5 QB's good enough to be drafted that early: Bortles, Manziel, Bridgewater, Carr, Savage.
I don't see why any of those teams would need to trade up to get one of the top QB's.
But you know how that song and dance goes: one of those teams, maybe two, will fall in love with one of the above group, and will feel it has to be that guy for them. So they'll trade up, and the fun will begin.
