You're absolutely right!
Another thing I would like to point out is, Cam was right, the Giants did nothing special at all, scheme wise, to stop the Read Option, they just have the horses up front that could individually blow it up.
It truly did come down to execution, although I think Cam was overwhelmed with Osi's speed and JPP's power and range at times, hence his hesitation when reading them.
Those ends sold out on the run. There was room to pass but Chud hates short passes and Bell was sorely missed.
