Gotta agree with GatorGuy, although Merriman had a little help from his friend Mr Steroid Needles.
Teams know what they're getting with Adams, what you see is what you get. He led the ACC in sacks. That's not a knock on him, but you want a player with high potential, not one that is virtually capped.
I can see Harvey being a speedy pass rusher for someone in the NFL like Dwight Freeney, only a bit bigger.
