College accuracy does not translate to NFL when you aren't running a pro offense. Tim Tebow averaged over 66% completions during his college career. Thats because he ran a spread and was throwing only to wide open receivers. In the NFL, Tebow averaged an eye poping 47.9% during his 3 year career. So there should not really be a surprise that Griffin is doing poorly when he is being asked to operate in something different from his Baylor kiddie offense.
