What concerns me is that word out of Browns camp is Manziel has had a steep learning curve learning to play under a pro style under center O. From a knowledge of the O, Manziel isn't ready. He doesn't yet know the O. If that is the case, and he still looks good...what happens when he does know the O...does get used to playing under center. Personally, if I was Cleveland I would avoid the temptation of playing him too soon. The Steelers will fold him like a pretzel if he hesitates. I could see Shazier or Timmons putting the big hurt on him.
