I just played NCAA Football 06, to see how it was in comparison to NCAA 07, and I was amazed at the differences.  NCAA 07 has truly improved in many aspects that I had forgotten had been flawed in 06.  For example, the running game has improved so much in 07, that running in 06 seems so far behind in terms of realism, even though it is only a year old.  That, along with other things, allows me to realize what a great job the development team did on improving NCAA 07.  Now if they could only fix the momentum meter for next year, as well as making the "jump the snap" feature a bit more realistic. 

Also, just to bring it to attention, the I-AA rosters for 07 are the exact same as the I-AA rosters from 06, which is disappointing that EA Sports couldn't have updated their rosters.
