And all three of those guys would blow by Bobby Carpenter like he was concrete shoes in man on man. If you're guarding those guys with a outside linebacker 1-on-1, something has gone wrong.
Pettiti owned Dwight Freeney, but Freeney has still managed to have an okay career in the NFL.
I don't know where the Erasmus James reference comes from. Erasmus James had 1 productive year in college and a long list of injuries (and he didn't have a bad rookie year). Kiwi has had sack totals of 9.5, 11.5 and 11.5 sacks and tons of QB pressures and TFL's over the last 3 years. Production and achievement has never been a problem for him. Does he have bust potential? Yeah, the same way David Pollack has bust potential. They don't have prototype bodies for their position, and might require a position change. But when you have great college production, great intelligence, great athletic ability and a great work ethic it minimizes the risk. Especially when you're picking in the late teens.
