Yeah, it's crazy but folks have been saying that since he came into the league. I'm not 100% sure on this, but the prior 2 seasons he was basically hurt on bull-rush QB pressure. His ability in the open field is crazy good....like trying to catch a waterbug in a pond.
I dislike the Ratbirds the most, but I reluctantly am going to give credit where it's due- Lamar is the best dual-threat QB the NFL has ever seen.
