I guess he had the lowest "time to pressure" in his draft class. Less than 3 seconds on average. Next closest was 3.8 seconds. I think he was 3rd in total pressures as well. So, he gets in the backfield often, and when he does, it's lightening fast. Add he's only 20 years old. I guess you can understand why the Browns loved him and apparently passed up on a ton of phone calls offering them ways to get back into the 4th round, but they felt too strongly about Hall to chance it.
