I really wanted to put Alonzo Spellman in this spot, but in the end I had to go with Julius Peppers. Even though he only played four years in Chicago, he was a beast for those four years. Signed as a free agent after eight years in Carolina, he came to Chicago and made an immediate impact on the defensive side of the football. He was a First Team All-Pro in 2010, a Second Team All-Pro in 2012, and was a Pro Bowl selection his first three years in Chicago. In just four years with the team, Peppers is ranked ninth on the all-time team sack leaders list. He also won the coveted Brian Piccolo Award in 2013.
2010: 16 games, 2 INT, 1 yard, 3 forced fumbles, 8 sacks, 43 tackles
2011: 16 games, 4 forced fumbles, 2 fumble recoveries, 11 sacks, 33 tackles
2012: 16 games, 1 forced fumble, 4 fumble recoveries, 11.5 sacks, 32 tackles
2013: 16 games, 1 INT, 14 yards, 2 forced fumbles, 1 fumble recovery, 1 TD, 7 sacks, 31 tackles
Runner-up: Alonzo Spellman
