You realize that a lot of **** good coaches aren't players, and climbed up through the ranks like Diaz, right? Mike Leach wasn't some muscle head jock, same with Lincoln Riley, albeit Riley was a walk on in college. Coaches now are more analytical than the old guys, but they can also figure simple crap out. It isn't how Diaz came up that is the problem, it's that Miami shouldn't have settled for this guy without doing a single outside interview. For the first time in decades, Miami had the pick of the litter and the budget to at least make a legit run at guys and chose to pick Diaz. Could Diaz turn this around? Maybe, but it's hard to think that a guy that spends this much time BSing on social media can be anything special.
