Out of the top# 4 QBs, I think Mayfield has the biggest chance of falling out of top# 10 unless a team trades up to get him which is possible like Miami. I would hope Plan A would be either Darnold or Rosen which would require the Bills to trade up to #2 to make happen. Plan B I would hope is Mayfield/Allen and trading up into the 6-10 range.
