Clay has 13 sacks, 3 turnovers caused, 4 passes defensed and a TD in 13.5 games as the main guy to block, and he's not even pass rushing all the time. Kampy's best year was 15.5 sacks in 16 games with 3 turnovers caused, no passes defensed and no TDs.
Clay also has as many 10+ sack seasons after 2 years as Kampy has in 9. The kid is outstanding.
