Logan Mankins, LG
How good is Mankins? After holding out for eight weeks, he returned to help stabilize the Patriots offensive line en route to an All-Pro season in 2010. His peers and coaches respect him that much in a position that is by no means glamorous. With Mankins on board, the Patriots allowed only 25 sacks and 52 hits on the quarterback. Tom Brady can wipe the sweat off his brow now that he knows he'll be back.
