because i look at the offensive minds Grimes has worked with and the schools hes been at. Boise State (great offense when he was there), BYU (had a good offense when he was here), Worked with Helfrich who went on to coach Oregon who is "totally" known as being offensively terrible, Won a title with Auburn, Worked with Les freaking Miles the mad hatter himself, and finally Matt Canada who is great with his spacing and motion.

Ty on the other hand was a "coach" for 14 years in the NFL and coached a highschool team. Grimes is lightyears more qualified.
