#1. Timmons. He had a breakout season. He was everything they hoped when they drafted him. He didn't let himself get all fat and out of shape, ala Woodley. He played well all season.
#2. Lewis. Finally a young DB developed.
#3. Allen, see above.
#5. Clark. Biggest reason the D held it together with all the injuries as it did.
Those who didn't cut it this year.
Ben, Wallace, most of O line, Polamalu, Tomlin, Haley.
