That last line is where I've been.
This isn't the players. It's coaching a significant amount of talent to get consistent results, or it's recognizing if perhaps a lack of talent exists, how it can be schemed around and not completely screw up the entire season. Which may already be too late at this point.
Sark stubbornly repeats failures. The deep pass for example. Quinn couldn't hit it for shit, yet it happened every damn game over and over. Arch actually can hit it, but the running game and OL is so bad it doesn't matter. Or Arch locks up.
All of that is coaching. And Sark for all the great he's done here is revealing more and more he's not a particularly great coach and doesn't get the best out of players.
Or his coordinators don't and he's not organizationally recognizing it and repairing it. It falls on Sark. PK is clearly great, Florida notwithstanding. Everyone else on the staff? Not much evidence to support it.
Sark's inflection point is now, or already underway. The 2-8 vs Top 10 opponents out front should also have told you.
