I agree. For the Colts to trade down to 12, Buffalo would have to offer us WAY more than moving up 6 spots usually would cost.
The Colts would be giving up a sure thing elite player and be taking more of a gamble at 12, and the Bills would be moving up to get their franchise QB. For the Colts to even start considering moving down, Buf would have to offer something like both their 1st rounders, both their 2nd rounders, and next years 1st. maybe even more
I like the idea of a Nelson, Chubb, Barkley BUT 2 1st round, 5 2nd round, and 2 1st next year sounds intriguing
