25. Clark Haggans (2000-07) - 107 G, 61 GS, 32.5 sacks, 206 tackles - I was never a huge fan of Haggans, but he did have his moments. Plus, he held down a starting OLB job here for four years, which is quite a resume builder in this league.
24. Carlos Emmons (1996-99) - 51 G, 31 GS, 12 sacks, 103 tackles - Emmons had the unfortunate role of having to replace Greg Lloyd and was a bit disappointing in comparison. The truth was he was a fish out of water in a 3-4, and went on to have seven more solid seasons as a starter for the Eagles and Giants.
23. Kendrell Bell (2001-04) - 47 G, 44 GS, 18 sacks, 193 tackles - Bell came out of the gate strong. Winning the DROTY and going to the Pro Bowl his rookie season. But, he declined form there. He had a mediocre second season and an awful third season. After an injury and attitude issues, he was allowed to leave in free agency in 2004, and finished his career with three mediocre seasons in KC.
22.Henry Davis (1970-73) - Davis played in every game in his four seasons as a Steeler. Defensive stats are not easy to find from that era but he did have four interceptions, and he was a primary starter for three of his seasons. Davis was a solid tackler, by all accounts, and was beneficial to Jack Ham's progress as a young player.
21. Jerry Olsavsky (1989-97) - Olsavsky was a guy who gave it all every play in practice, and every play on the field his entire career. Definitely not blessed with the size and physical attributes of many of his counter parts, Jerry had a simple plan for success; out work every other guy on the field and quite often he did just that. He played in 119 games and started 37 during his time in Pittsburgh, he had 206 tackles and four forced fumbles. The numbers would be better had he not suffered some major injuries in the prime of his career. He has joined the Steelers coaching staff for the upcoming season.
