SF had to make the trade for Dee Ford because their best bet, even better than taking Quinnen or Bosa, is to trade down with the Giants.
Arizona is drafting Kyler Murray, we all know that at this point.
As evidenced by the departure of OBJ and Landon Collins, New York is ready to start over which means they need to move up and take their QB, Dewayne Haskins (who knows maybe they prefer Drew Lock or Daniel Jones but I doubt it). The picks they just got for OBJ will obviously help them seal the deal with John Lynch.
What this means is...
1 - ARI QB Kyler Murray
2 - NYG QB Dwayne Haskins
3 - NYJ
4 - OAK
5 - TB (guaranteed to land one of Bosa, Quinnen, or Allen)
My guess is Jets go Bosa, Raiders go Williams, and we get Josh Allen.
