If Diaz wins here hes going to do so on his ability to adapt and recruit. Criticise all you want, he's a much better recruiter than Richt - I'm genuinely not sure what he's sold some of these kids, but he's brought in two very good classes.
He runs an aggressive and largely successful defensive scheme (yes it's flawed, but good athletes hide that) and he's hired a good Spread OC. Literally everything people have asked for from Miami.
That said he's not a coaching savant and is clearly learning how to be a HC on the job - that's Blake James' fault, not his. We were in dog fights last year because Jordan couldn't stay healthy and Pope / Wiggins dropped everything. Get players in those matchups that can win their one-on-ones and we blow out a few of those dogfights. College football really is that simple.
TL;DR I've seen Diaz try to correct his mistakes every year and general improvement on the field / in recruiting. If we don't win the ACC Coastal this season then I'll get off the bandwagon - and that means I'll only accept close games against VT, UNC and NC St. Against everyone else we should be emptying the benches in the second half.
