The Patriots cut Wilfork last year, indicating the end might be near. However, the 325-pound lineman started 16 games for Houston. He is coming off a down season for himself -- 22 tackles -- but remains one of the Texans' key cogs along the defensive line, especially against the run. With big question marks at defensive end opposite J.J. Watt, Houston needs another season or two from Wilfork to stabilize the front seven.
