The coverage with the best chance of stopping the screen would've been Cover-1 (Man with a FS deep), which we've run a fair amount in some other games. This was the first game with an obvious BBDB gameplan. In terms of pure X's and O's we had a 3-on-2 advantage over every one of those screens except the jailbreak screen at the end of the 1st half. The problem is the second underneath defender, usually the OLB. If they have two WR's out there, he's the second underneath defender who's matching up. The problem is that, because of the run, we weren't pulling that guy out all the way to the #2 WR, so he had a natural disadvantage against every outside screen. This problem would be partially solved by faster OLB's/guys who took fewer false steps in addition to CB's who could shed better. Put another way, other teams line up in the same way against our screens but blow them up, which we were completely unable to do yesterday. It's also a mystery to me that our safeties couldn't make more of those plays, because that's exactly what they did when UA ran plays like this. Our safeties were surprisingly ineffective against these screens.
The issue in all this is the run, which was also killing us. Hundley's reading those flat defenders (OLB's) pre-snap. If they go outside to match the screen better, he hands off, usually getting 6-7 yards. If they pinch inside, he throws the screen. The OL is run-blocking on every one of those plays. The only real way to combat that would've been Cover-1 nickel. By taking a safety out of deep coverage, we put him over one of the #2 WR's. This means that a LB doesn't have to remove from the box on that side to match numbers, so we can leave 6 men in the box against the run while matching numbers better against the screen. We've run Cover-1 a lot this year, so against UCLA we were probably avoiding it (1) because of our bad tackling in the game, and (2) because of the mobile QB. In Cover-1, since it's straight man coverage, if you miss a tackle it's a huge gain. A more aggressive coverage would've helped the numbers problem against the screen, but putting extra guys out there yields a bigger gain if one of those guys misses the tackle Also, it takes four of your defenders' eyes off the QB and puts a fifth guy (the FS) deep and out of run defense. This is a problem, because we still only have six box defenders against 5 OL + 1 RB + 1 QB. We'd really need a 7-man box to feel great about stopping both Hundley and the RB. We can only get to a 6-man box because of the spread formation, though, so playing zone is intended to limit the run to medium-sized gains when it gets through those six defenders.
In general, our entire gameplan was conservative against UCLA, including punting so often near mid-field. That strategy could very well be why we were close enough to win in the first place, though, so it's hard to say.
