He won't be a 1st rounder which means either the Browns, 49ers, Bears or Jets won't be drafting him, unless one of them signs Jay Cutler in FA. Also one of these teams is likely to trade a 2nd for Garoppolo.
I think Kaaya goes in the 2nd round to one of Chargers, Saints, Cards, Giants, Chiefs, Steelers, or Pats.
If I had to bet I'd say he's a Cardinal.
