Panther247 brings you another update on the Top 10 Former Pitt Panthers in the NFL through Week 4. Our last update was on Sep. 20, after Week 2, and there's been a good amount of shakeup in the rankings since then.

Buffalo Bills second-string quarterback Nathan Peterman didn't make the cut this time around. Peterman was benched after a horrible Week 1 performance and hasn't seen the football field since for the Bills. Taking Peterman's place in the rankings is his teammate Ryan Lewis. Lewis, a defensive back, has been solid in his last two starts for the Bills and makes his debut on the list this week.

There's also been some shakeup in the rankings itself. Veterans LeSean McCoy (Buffalo Bills) and Larry Fitzgerald (Arizona Cardinals) both have had a rough couple of weeks. Running back James Conner has not been able to duplicate his Week 1 performance in the past three weeks.

Check out this week's risers and fallers.
