I would instantly trade for Tong Ugoh - former starting LT for the Colts who was benched not because of poor play but his former backup is simply better now, and Derrick Johnson - a very good 4-3 LB who is now on the bench because of the 3-4 switch, think J. Vilma.
In one day the Bills would have added a veteran LT who blocked for the best O in football, and an athletic LB who can keep Ellison on the bench. This would cost MAX a 2nd, 4th, and maybe a 7th round pick.
Once more, these are moves that could be done TODAY by the current folks in charge. Why commit to winning?
