"On December 13, 2018, Diaz was named the 28th head football coach at Temple University, replacing Geoff Collins, who left to become the head coach at Georgia Tech. However, he left the team just two weeks later to return to Miami and was named head football coach on December 30, 2018." Source Wikipedia
This alone makes it enough for me not to want Diaz. in addition he is a rethread and was at best average as a HC at Miami. So no for me
