I'd guess they are one elite coach away from being relevant again. The kind that grows on trees ...
they just need someone that will identify and keep the cream of the crop at home. like they used to. nowadays they lose everyone they really want to Ohio State, Alabama, LSU, Georgia, etc..
They probably win at least 1 national title with you or me coaching if they keep just these 10 players in their backyard home from the 2014 - 2017 classes (4 full cycles- a full roster for a coach)
QB - Lamar Jackson (Boynton Beach, FL) - 1st rd pick, Heisman trophy winner, NFL MVP
RB - Dalvin Cook (Miami, FL) - 2nd rd pick
RB - Sony Michel (Plantation, FL) - 1st rd pick
WR- Jerry Jeudy (Deerfield Beach, FL) - 1st rd pick
WR - Calvin Ridley (Pompano Beach, FL) - 1st rd pick
LB - Devin Bush (Pembroke Pines, FL) - 1st rd pick
LB - Josh Uche (Miami, FL) - 2nd rd pick
CB - Trayvon Mullen (Pompano Beach, FL) - 2nd rd pick
EDGE - Nick Bosa, (Fort Lauderdale, FL) - 1st rd pick, NFL DPOY
EDGE - Brian Burns (Delray Beach, FL) - 1st rd pick
Miami offered all those guys. Got
none of them. That's eight 1st rd picks and two 2nd rd picks. They tried to get Lamar to play another position, he said no thanks. Imagine that. Bad decision. Good luck stopping that backfield with that QB and RB duo, can't double both those #1 WRs, that
serious speed at LB, you don't have a prayer blocking that edge rush duo.
You can do that with basically any 4 full classes with guys just from their backyard in Miami, Broward, and Palm Beach and you'll have 10+ 1st or 2nd rd picks that Miami missed out on in their own backyard.
