I think Richt is going to be the Buck Showalter of college football. Great manager, gets a team going in the right direction, can't win a championship, gets replaced, next guy wins championship the following season. I have no doubt that Richt will refill the cupboard by year 5 and Miami will have very good to excellent talent at every position. He won't have all elite talent, but you don't have to be elite everywhere to win a ring if the rest of the team is very good.
Year six Miami brings in an innovative coach, who runs a high tempo spread offense. Miami speed blows teams off the field. New coach lands 1-2 elite kids (kind that will takeover a game), and he wins multiple rings with Richt's players. Williams will be a RS Junior year 6 and will be a Heisman candidate.
Long story short, I've come to terms that Richt is the coach we need at the moment, but I've made peace with the fact that he isn't winning a ring. That's doesn't mean we made a bad hire, because the next guy will be inheriting a loaded team thanks to Richt and we get number 6&7.
