Brent V is a front 7 guy. Both Mike and Bobo are back 7 guys. Brent got tired of fighting both Bob and Bobo. Plus he grew into a better defensive guy then both Bob and Bobo. Then add, Brent is better at sniffing out talent at LB then either Stoops. And of course he played LB, something neither Stoops played.
Bob and Mike will take a chance on a DB way before they will take a chance on a Dlinemen.
Right now it's just important to simplify the defense and let players play. They were fundamentally sound, playing in a vanilla D, against FAU and UCLA. The huge problems didn't come until we opened the play book against ISU. If you have to think about what to do, then you don't know. Way to many one or two position react schemes. That's a DB, LB, Dline having to adjust on the fly, depending upon what one or two position do.
A DB pushes the outside edge, if the DE crashes the edge but the LB has to slid over to fill the gap. But the LB doesn't so now he has to think, instead of play. That does not come naturally and takes 100's of reps to flow. Then they are thinking and not playing just the fundamentals. ie tackling, or void fill.
Just look at Bolton sack, The DE gets manhandle and Bolton is suppose to gap or void fill. He went for the void and the DE, getting manhandled, that took away the Texass screen. So he gave up void and went for the sack. That was a busted play on the D. That wasn't a delayed blitz but an out and out busted play on our D, that we just got lucky. He's a 5th year senior so that experience, might have helped but he had a clear path and sat for an extra second, before he committed. We got lucky.
You are absolutely right. Mike was way too complicated for his own good and I heard stories about how they’d practice one way then change their gameplan on a Friday. When we have players out there looking on the sidelines trying to find out where to line up... it’s too much and too complicated. They should be lined up and ready to fire off the ball. I totally concur with your whole post. I really hope Golding is the new DC.
