I just posted a similar, if imperfect trade on Reddit, and it is getting slammed for obvious reasons...but the theory is if there are only 2 Blue Chips and 10 1st round graded players like some FO supposedly think, a small trade down basically takes out out of 1st round talent and doesn't net much. Why not trade as far back as possible, still get about the same type of talent but more of it, or '26 picks that maybe in a better class.
I think Hunter is the only one that maybe available at 4 that might be worth someone trading up for....the QBs aren't great, if Carter is there we should take him. If Hunter and Carter is gone, the next group of players are a step or two down. So see about trading the pick to someone in the back third of the first. Lots of teams need a CB1, and with a more talented roster getting Hunter touches as a gadget Offensive player would be acceptable.
I think this list is correct, both for CB needs, and 2nd round picks avaialble:
The Jimmy Johnson chart would be #4 worth #30, #56, #62 and a '26 2nd. Now maybe the Bills want to change one of the '25 2nds to a '26 1st. Is it enough value to basically punt on the 1st this year?
Of course you can say no one will trade up to #4 for a CB...but if he is the #1 or #2 player in the class?
