Who Bonnell? he knows no more than anyone else that isn't in the front office of the organization. If it was known who everyone wanted it wouldnt be a draft. of course you have an idea of who wants who, but look at the NFL draft with everyone thinking Bills and Nassib they trade down and take Manuel at 16. It is always a guessing game.
All I am saying is if the team feels Len is the guy then take him at 4. No point in trading down and risking losing him. Trading down 2 spots wont do anything but put you in danger of losing the guy you are targeting.
Now lets say pick 7 wants Bennett, and we are ok with getting him and we take him. Then pick 7 takes Len and we swap and add pieces by all means I am ok with that. I am not ok with trading down and hoping we can still land our priority target.
