All the teams below us have a reason to want to trade up to jump a rival for a player of a certain position.
QB) 49ers Eagles and Rams RB) Eagles, Giants and Dolphins OT) 49ers, Eagles, Giants, Buccs, Bears, Dolphins and Raiders etc
I would only trade back if Bosa Jack Ramsey and Tunsil were gone. I wouldn't want to drop back any further then 15th as I believe the advantage gained in adding picks is diminished by the drop off in players talent.
Trade with 49ers to no7 where we could swap our 3rd rounders and gain either their 4th & 6th or both 5th & 6ths.
Trade with the Eagles to no8 to gain their 4th & 6th.
