If you want to learn something about how modern defense is played, especially in the Big 12, you need to be reading MatchQuarters.com. The author is currently a Texas HS coach who worked previously as a GA at Baylor under Phil Bennett. You may hate Baylor and Bennett, but the man has used a quarters scheme that borrows from Michigan State, TCU, K-State, and even dikk LeBeau to build a defense in Waco that has been getting pretty good over the years and may have them in position to contend for the Big 12 title again.
Coach Alexander has been writing recently on quarters defense and
why it's a superior scheme to base single-high safety systems such as you can find drawn up today in Bellmont.
The basis of his argument can basically be summed up as:
1. Quarters makes it easier for the defense to line up sound to any look.
2. Quarters has built-in versatility that can allow the defense to shift help to lock down different offensive threats all from the same 2-high initial look, or to adapt to different personnel.
3. Quarters is easy to line up in and play fast without being too simple, even against up-tempo spread teams.
4. Quarters lends itself naturally to running the kinds of man/zone blitzes that are starting to become a best practice across the game.
If you are hesitant to accept this you might consider the success that 2nd tier teams such as Michigan State, Baylor, Kansas State, and TCU have had running this system. Or the fact that Gary Patterson was able to keep TCU chugging along last year with a 190 pound converted safety playing linebacker. Some of that is coaching, but the system sure doesn't hurt.
I'd argue that Vance Bedford has a pretty strong idea of how to stop spread offenses in his own right, but there's little doubt he's had some struggles adapting at Texas. I could be off but I have a suspicion that Vance has two main struggles as a coordinator that he's been unable to cover up over the last two years.
The first is a predilection for trying to create opponent-specific packages rather than having a scheme that can easily adapt to a given opponent without needing major changes. We've seen that lead to disasters this year already, even though on paper his gameplans for both UTEP and Cal were quite good and made great use of the skill sets on the roster. The problem is in translating that kind of variance to consistent performances week to week with a roster full of 18-22 year olds.
I'm not sure his style really works well with young teams of underclassmen. Take the performances of his defenses over this decade measured by S&P:
There's reason on that chart to believe that a team which isn't stocked with veterans who know how to put the time in from week to week and handle Vance's wide array of schemes isn't going to be consistently great. Of course when he does have the pieces he needs, he's put out some elite units.
But just take a glance at what Brent Venables (who uses quarters) has done over the same period of time:
Despite regularly turning over much of his roster and sending kids to the NFL, Venables keeps putting out top 10 units. Eat your hearts out Sooner fans, you had the goose that lays the golden eggs and you traded it in for nepotism. Once Venables had his program in place at Clemson they were off and running, he's arguably the best defensive coordinator in the country.
The other problem I think Vance MIGHT be having (because I don't know, I'm only going off what he's said publicly) is a difficulty teaching what he wants effectively within the up tempo practice format that Texas has adopted to suit the new offensive system.
Now that doesn't jive with reports that the defense was beating up on the offense in fall practices, so that pokes a big hole in this theory, but it would make sense of the difficult that Texas' secondary has had at times with some rather basic coverages over the last few weeks. Perhaps the week to week variance of packages is enough to explain that without also positing that Vance is struggling with up-tempo practices but it's worth pondering.
Now Texas' marriage to single-high coverages isn't tied to their marriage to Vance Bedford, it's a Charlie thing. Running single-high is what Charlie knows and it suits the current personnel very well, but quarters is becoming the "Air Raid" of defenses. Much of the league is turning to it for a reason and the reason is that it easily molds to different personnel from year to year while providing a sound base that can be executed from week to week.
So is Charlie going to figure out how to get Venables-type results with his scheme? Or does he start to reconsider his preferred defensive systems as he did on offense?
