It will be interesting to see how he works out at USD. Being an alum from there, I have followed them closely. USD got a new coach 3 years ago and had a great year last year with the runner up for the Walter Peyton award (FCS Heisman). This year, USD had some expectations and they didn't really meet them and had a very average year.
Next year they will have a their QB returning for his senior year and he had some pretty darn good stats. It will be interesting, because USD's offense seems to thrive with a mobile QB and Simmons just isn't mobile enough. USD has had similar problems to ISU, where the offensive line hasn't caught up to the team.
I don't know if Moore will be able to take the starting position, but I have a feeling he will be able to come in a push because of his mobility!
