I think its clear we cant just plug him in and automatically say he can be as good as Leon was. I dont think he is anything like Leon first and foremost. But my comparison is that he has the potential to be Felix Jones. I think he has the frame of Chris Johnson, hate to mention that name because the speed isnt close, and I dont think he can run away from everyone like Chris. But maybe he can break tackles just as good. He doesnt have elite speed, and he is not as low to the ground as other RBs, so I think its hard to find a potential comparison. Maybe even Jamaal Charles although charles may have better speed, Mcknight may have the foot speed which translate well in the nfl. We will see.
