Peter Schrager was desperate for the Bills to either trade up (so Kyle wouldn't get there on time) or trade out of the third on GMF, just for the spectacle of him making the journey for no reason.
Though it could be Jackson was told that they would never trade Brown, or at least not without a ready made replacement. Perhaps they'll go all in for Samuel.
Seems like Dallas had lined themselves up to pick him, or at least that was the concern - hence the trade up as he was the final first round corner we had on our board.
The Browns are now seeing a chance to offload Mayfield.
Considering how the clock ticked down I think the Panthers wanted to move down the board but had no takers.
