Kyle Williams would be one of the first guys I would keep and find a place to put him. I'd go back to a 4-3 if it was the only way to put him on the field. Can't think of anybody that works harder.
On Defense I'd also keep Scott, McGee, McKelvin, and Bryd. Scott may not start, but he's another player that works hard.
Offense would be Spiller, Evans, Wood, Levitre, and McIntyre.
Lindell and Moorman are givens.
On second thought: I'd also consider keeping David Nelson, Parrish, Shawn Nelson. I'd have to see some more playing time from some of this years rookie class for some of the Defensive guys too.
