Giants easily. Colts second.
If Grigson is fired, I'd rank them:
Colts (Andrew Luck is way younger than Eli and I believe this year was a fluke for him)
Giants (Defense is a mess, but Eli and OBJ make this very attractive regardless)
Titans (young potential franchise QB already, which is the most important part of a team)
Eagles (QB situation sucks)
49ers (Kap is huge ? But at least we have a fuck ton of cap space and a stable F/O, although not a patient one...Not as dysfunctional as the Browns though! and slightly less dysfunctional than the Dolphins with Ross/Tannenbaum, but feel free to disagree with me here)
Dolphins (QB situation sucks and Suh is a fucking huge cap hit)
Browns (The Coach helps hire the GM, fucking WHAT?)
If Grigson retains his job, I'd move the Giants over the Colts.
