Saw this posted by on another site. This guy doesn't say where he coaches buy gives a great breakdown of Bama after some games,
The thread was about what went wrong with Ty and the longer passing games and OL issues.
Lots of crossing routes that I’ve yet to see at Alabama
Those are typically man beaters. Most teams (not all) run man-2-man when they need extra people in the pass rush. That level of extra people in the pass rush was not needed (in general) against Alabama.
Most of the year, Alabama would not roll the QB to the edge. Ty was by design supposed to avoid the rush by moving up in the pocket from a shotgun 5 step drop. It worked for a while until the better DC's learned how to break it. Slants with twists to the middle. The OG's and running backs did not handle those stunts well and when Ty would move up in the pocket he was met with massive bodies and heavy hitters in his face and at his legs.
Eventually, Ty did not trust being able to move up in the pocket. When he got in the mode of attempting to slip the rush backwards or to the side, the DC's put more twist pressure on the tackles and speed rush up field. Tackles had to choose which man to block. Ty was watching for pass pro colapse as much or more than post reading the coverages.
Physically, Ty was hurting from too many bad hits. Mentally, Ty had no trust in his protection.
With big hitters at his feet, he no longer trusted he could plant his front foot and throw over it on deep routes. From pain, he no longer had the clean ability to throw with torso torque. When Ty passes over the top he has pretty good deep accuracy. When Ty tries to throw deep with torso troque he loses accuracy and the ball fades to his right. Deep left side throws fade toward the safeties. Deep right side throws fade to the sideline. Deep middle throw hang up or he muscles them and they over fly the target.
Ty revertd to what he trusted most. Good DC's took those away because they did not have to worry about the run or deep shots to the outside. Decent DC's could just follow what the better DC's had shown them.
Ty's game was cooked. Cooked physically and cooked mentally. He could still read the D presnap but he did not trust his blockers enough to read well post snap. His run adjustment reads did not matter as the OL could not block run well enough to overcome the lack of RB vision and short area exploision.
Kirby/UGA broke the Alabama offense with halftime adjustments in the first game. The decent DC's used that map the remainder of the season, if they had the players to execute the plan.
