Not sure which particular part you disagree with. But I'm sure there's plenty of material that's worthy of disagreement.
My main point is that your every decision has been based on the presupposition that you will have a dual-threat QB. When, in fact, almost no such QB's exist. And those that do largely go to Alabama, Ohio State and Clemson. Frost is trying to repeat the Milton McKenzie miracle. But that cannot reliably work. So you fail again and again.
Permit me to be more specific. You assume you'll have a dual-threat QB to fuel explosion. So you recruit "explosive" WR's who can't run precise routes, but can freelance and produce YAC. But you don't have a true dual-threat QB. You have a running back who can throw a little bit (Martinez, McCaffrey). ...So, now you have a QB that cannot throw the ball reliably paired with receivers that are not precisely where they should be precisely when they should be there - and who cannot "set up" cornerbacks with exacting route mechanics. With regard to the WR's, that's not their fault. They were supposed to be free-lancing explosive types who leveraged preoccupation of the entire defense (secondary included) on the QB. But that didn't happen. Because you ended up with a running back for a QB. Now the whole thing doesn't work.
And this will repeat itself again and again. Why? Because there are between 0 and 2 true dual-threat QBs throughout the nation every year. And you're unlikely to end up with one of them. SO STOP PREDICATING YOUR ENTIRE FUTURE ON LANDING ONE. You don't need one to succeed. It's not the only path - it's just the only path you are pursuing.
