Summary: If the Raiders pass up on Griffen in the first round, then he could very well fall to the second round. I have watched a LOT of tape on Griffen and the tape just isn't there to justify a top-20 draft pick. He's a soft football player and I question his love of the game with his physical tools. Griffen seems like a boom-or-bust prospect at the next level, and I'm not leaning towards "boom."
Player Comparison: Robert Geathers. Griffen doesn't have his motor, but he's an average defensive end with good athleticism. I see a similar career for Griffen.
