It's no secret that the Seattle Seahawks could see big turnover on the defensive line in the offseason, with both Ziggy Ansah and Jadeveon Clowney set to be free agents in March. Add in Al Woods, and the Hawks could be looking at needing to replace a very large number of snaps in the trenches. However, if the next twelve weeks play out the way the first four weeks of the season have, the player the Hawks could miss the most from the defensive line could be fourth year man Quinton Jefferson.
