Johnny Dingle (ha ha ha...I cant get over that name) might be worth a look if he falls to the mid to late rounds.
"Dingle finishes [this season] with 48 tackles (19 for loss) and nine sacks"
Edit: There is also Derrick Harvey who may be a good option for our first round pick.
2008 NFL Draft Prospect - Scouting Report
Harvey surprised many when he decided not to enter the 2007 NFL draft. He led the Gators with 11 sacks -- the fifth-highest single-season total in school history -- and capped the season off with a three-sack effort in Florida's rout of Ohio State in the BCS national championship game. He also had another tackle and recovered a fumble against the Buckeyes to earn defensive MVP honors. He was projected as a first-round pick by some analysts.
Harvey, however, felt he needed another season to develop -- he didn't begin playing football until his junior year of high school -- and started an extensive offseason training program that paid dividends this past season. He overcame being the focus of opposing offensive lines to amass 49 tackles -- 31 solo -- with 17 tackles for loss and 8.5 sacks, which were both team-best totals. He earned second-team All-Southeastern Conference honors.
Harvey is simply a beast as a pass rusher, with his speed equal to his strength. He is known for getting great jumps off the ball and his technique is exceptional. He puts the heat on offensive linemen and virtually demands to be double-teamed. While his ability to get in the backfield draws the most raves, he's also solid against the run. He projects as a lock first-round selection and will likely be a top-20 pick.
