To be fair I only watched a few highlight films of him.
With that said I see some Beanie Wells with more size and that upright running style position. I'm not crazy about it unless your AP. Ball is frustrating to watch because he doesn't have that next gear in the speed department nor does he run with authority (low contact runner). Goes down on first hit. Some mediocre bleh competition. Could make good in the durability department.
His hands are amazing and he knows how to execute a route and can turn the corner. Some solids to build on for sure but I don't know if he is a 3 down back in the NFL fellas.
