I was just thinking about this exact scenario...If it did happen, I would try to trade out if I could for extra picks. If not possible, Isaiah Simmons seems like a perfect chess piece or Okudah(if we didn't nab a CB in FA)
The word on the street though is that Gettleman of NYG does not trade back. That is what I am counting on.
I know that a lot of people think Rosen sucks, but there may even be a plan to give him one more year and build up a team around him. If that's the case, Miami would have the last laugh at all these teams thinking they were actually tanking for a QB. Because, seriously, Herbert and Tua are sadly not ideal prospects at this point. So if another team wants to give up picks to go get them, well, buyer beware.
They're definitely good, but...injuries and inconsistency are dangerous red flags.
