This is my first diary, I am sorry if the up to par. I'll attempt to get better with each one I make explaining things in better detail, or simplifying things if need be. Or futhering explinations on others.

Since JH was hired, I have spent time watching Florida game film seeing what type of defense Durkin might run. While everything you've read on him online says he runs a 4-3 scheme, from the tape I've watched I've come to the conclusion this is a 3-4 Under scheme almost akin to what the 49ers ran. I heavily broke down Florida's games against Alabama, Missouri, Florida State, and East Carolina to see how they've handled the four main offensive systems in football. A smash mouth run game, a spread passing attack, a pro style route tree, and a no huddle offense. I'll start this by showing his tape against Alabama.

What I've noticed is he doesn't deviate from 4 basic coverages. Quarters, Cover 3 Press, Cover 1, and his favorite blitz is the Fire Blitz from the QB's blind side. He hardly ever runs Man Under, Tampa 2, or Cover 0. He values speed and isn't against running a 3-4 with 3-3-5 personnel. After the first touchdown by Alabama, I found him running 3-3-5 personnel, on around 75% of the snaps, occasionally using a 4-2-5. While they'll never call it that, I expect the 3-3-5 to be Michigan's most used personnel grouping in 2015. I hope that doesn't scare anyone because this was one of the most fundementally sound defenses I've seen. I seen few blitzes out of him, he sent 3 on more snaps than he sent 5 on. He makes that up by changing which 4 he sends and by rotating out his players a lot. It's not 

On Alabama's first snap of the game they broke with 11 personnel, which is 3 WR's, 1 TE, and 1 RB. They created a twist by showing a Empty look, and then motioned the TE to the opposite side and the Mike followed him in man coverge and was out of place immediately post snap. They were in a Cover 1 with the Sam & RCB playing Press, and the LCB and FS playing off. Alabama runs a screen to the right with the TE and RB with the opposite side doing what the defense presumes to be a Shallow Cross. The Mike who was assigned to spy Sims dropping back to take away the first read, and the screen being well covered, Kenyan Drake ran a well timed double move route beating the cheating LCB and SS deep for an 87 yard touch down.  The SS being out of position stemmed from the motion pre-snap, he looked there immediately post snap becoming flat footed and out of position deep.

On Alabama's third drive of the game they faced a 2nd and 3. As usual with Alabama they rolled out a 6th OL and a TE in the pistol. Florida responded with their usual 3-4 Under look, but with a unique twist they subsituted a LB for a safety in the box. They also only had 10 men on the field for this snap. That doesn't matter as much because this play is a schametic marvel. Alabama is running a Run, Option, Hitch play. Where Sims can hand it off, keep it for an option, or throw a quick out/hitch to either WR. They crash of all their LB's into the gaps and left the WR's on man to man coverage. Instead of press, they back up the CB's almsot forcing Sims to throw the quick out which is the correct read based on the defensive look he was seeing at the time. But, to his surprise the subbed FS immediately pull up, and the CB crashes causing what should be an automatic first down just a 2 yard gain. 

Later in the game facing 2 WR - 2 TE - 1 RB, Florida comes out in the 3-4 Under look again, once again with an FS subbed in as a LB. Once again the LB's play sound gap technique forcing only a 2 yard run on an inside zone. Alabama calls a no huddle, and runs a play action off ot the inside zone which the FS immediately sniffs out playing perfect contain on Sims getting 5 yards of penetration as soon as the fake was done. This forced blake to nervously throw the ball away which was tipped and intercepted by Florida's defense. Subbing in the speed of a FS to play contain absolutely amazing adjustment against a team that was running Inside Zone and showing Empty looks out of the same 11 personnel. 

Finally,in a tied game on a 1st and 10 Alabama ran no huddle after a 3rd and 1 pickup with 6 Offensive Linemen, a TE, 2 WR's, and a RB. Florida responded by bringing 9 in the box, arguably 10. Once again the FS is playing as a LB in his 3-4 under alignment. Blake audibles out of the run into a play action. I find this play interesting because not one player became flat footed and fell for the play fake. The Ends pinned their ears back and rushed down field, and the LB's immediately went into coverage. As Sims is finishing his 7 step drop back, the end meets him 10 yards in the backfield on his blind side. He ends up sacking Sims while the rest of the defense plays a Quarter with inside releases forcing the entire play to develop inside of the hash marks keeping sims relatively simple, but also garuanteeing he stays within the pocket.
