Alternatively, have the students (Meyer, Kelly, Kelly et. al.) surpassed the teacher (RR) of the spread?
Before formally asking this question, one giant caveat, one in fact that some may say explains away this issue completely: these coaches are working with proven, experienced QB's and offensive players with more experience in their systems than Michigan's.
Now to my question. It seems to my (never coached) eye, particularly watching the Oregon game last night, that I see far more creativity and variety in the offensive sets and plays from Oregon, Florida and other Rodriguez spread offense disciples than I see in our offense in year two (repeat caveat above). There have been several times this year, even against Illinois, where I said to myself "wish we had that set in our offense."
Do the former coaches who post here, or other x's and o guys, agree?
EDIT: This is not criticism in any way of RR, just a speculation that it looks to my eye that some guys that learned from him may have taken the ball and improved even more on the template of the offense.
