Center is nowhere near our biggest need. When our line was healthy, over the last 7 weeks of the season, the Bills recorded almost 150 yards rushing per game. I don't know where you're getting your info from that the 3-4 defenses in our division are stuffing the run against us, because we gained 187 rushing yards against the Jets and 161 yards rushing against the Patriots during that stretch. I repeat, center is nowhere near our biggest need.
Our lack of a pass catching tight end, invisible linebacker corps, and defensive ends that seem to have concrete in their cleats are far more pressing areas that we need to improve.
