Most analysts have disagreed with Donovan McNabb’s declaration that Mike and Kyle Shanahan will not be able to make Robert Griffin III a successful NFL quarterback. Few have done so with quite as well as Michael Lombardi of the NFL Network.
It’s a long piece and you should go read the whole thing. But here is the key paragraph:
However, Shanahan is smart enough to know that the blueprint he has in mind for Griffin will change daily because he will learn more about what his new signal caller can and can't do well. Shanahan will eliminate all the things that are not suited for Griffin's game, and inherently highlight the things that work well. Much like Reid did for McNabb -- which, again, makes me ask why McNabb thinks it won't work with Griffin and Shanahan?
Imagine that, adjusting an offense to a player’s strengths.
