My theory on this is that in the Big12 we saw more 3-3-5 so it was less pressure coming from the D-line, and pressure that came via blitz from the LB was easier to see/diagnose and get one extra beat to react to. In the SEC the D-lines are bigger and faster, the coverages are more multiple with better athletes, and the pressure is showing up faster making it harder to read/react.
I was watching a QE's high school highlights again:
Watch the first 10 or so throws on the tape here and you're going to see a lot of the same issues we see now. I see a TON of back-foot throws, and also not climbing the pocket. There is also some dimes in there too. But if you look at the >20 yard throws, many of them are either 1) the WR is wide-ass open, or 2) it's a lob that the WR wins. In college you don't get hardly any of #1, especially on deep shots. And for #2 the CBs are such higher level how and the safeties so much faster that those lobs turn into picks or breakups - which is exactly why he isn't throwing them. It's almost like he's using a 9-iron angle on those throws when he needs a 3-iron. When he attempts to lower the angle, he overthrows it. For all the touch he has on the short and intermediate he doesn't have it on the long ball.
Sark and QE have to figure it out because it's pretty obvious what defense we're going to see the rest of the year:
Pre-snap show 2 safeties high
Post-snap rotate one safety to close the middle of the field to intermediate crossers
Blitz a LB to create pressure, or simulate blitz often
Show man and switch to zone or vice versa, QE has trouble (like many QBs) when a pre- and post-snap read don't match up
Deploy a shallow zone and expect the check down to the flats
Keep it all in front of you
This plan basically forces QE and Sark to do what they don't want: attack the sideline downfield with long throws, or go over the top. Normally the counter would be run the damn ball and force them to shift, but we apparently don't have the horses for that.
