What's wrong with KU's defense? Examining the issues against Oklahoma State
For this blog, I have consulted a Div. II offensive assistant coach, someone we'll just call "Coach."
For this week's breakdown, I pulled out three successful offensive plays from Oklahoma State in its 70-28 victory over Kansas.
My question to Coach this week was simple: What stands out most to you as the breakdown on each play?
Coach says two things immediately pop out on this touchdown pass from Brandon Weeden to Justin Blackmon.
The first is the position of KU's defensive linemen when the ball is snapped, as all of KU's defensive linemen are not set.
None of them are in a typical three-point stance with a hand on the ground. This is a result of OSU's fast-paced offense.
Starting like this, KU's defensive linemen have little chance of being able to get leverage against OSU's offensive linemen.
"That’s why defensive linemen are in three-point stances," Coach says, "so they can fire off the ball and get a good push against the run, or even against the pass."
OSU's receivers make two good blocks on the outside, but the second thing that stands out most to Coach is the angle taken by KU safety Keeston Terry, who is unblocked.
If you watch the video again, Terry rushes up to the line of scrimmage to tackle Blackmon before circling back as the receiver runs by him.
He essentially takes a horseshoe route (red arrow) instead of taking an angle to where Blackmon is going (blue arrow).
"That’s a poor angle to the play," Coach says. "I always tell my guys, even when we’re blocking, take an angle to where the guy’s going, not to where he’s at, because the guy’s obviously moving as well."
Coach says that defenses typically work on pursuit angles in practice.
"Sometimes, (offenses) are going to get you on a play, but make the play a five-yard play or a 10-yard play," Coach says. "Don’t turn every single big play into a touchdown."
Let's move to the second play — a deep pass down the sideline from Weeden.
Coach says what stands out most is KU's front three.
"Obviously, they’re not getting any pass rush at all," Coach says. "It’s hard when you give good quarterbacks time to survey the field and time to throw, because a lot of times they’re going to find an open receiver, even if you are covering with eight."
Coach estimates that Weeden would have had at least three to four more seconds to throw the ball if he needed it, based on penetration of KU's defensive linemen.
Essentially, KU's nose tackle is being triple-teamed, which leaves the ends one-on-one. Neither gets within a few feet of Weeden when he releases the ball.
As for the coverage, Coach says it appears KU's Greg Brown is playing man-to-man press — a coverage usually reserved for blitzes or when a cornerback knows he has safety help.
With eight defenders to cover five receivers, Coach says there was some sort of "mental bust" on this play. Most likely, it was one of two things:
- The corner was supposed to be playing zone.
- The safety was supposed to help over the top of the route and didn't.
Coach says either way, this play was doomed to fail with as accurate as Weeden is. Give a good quarterback that much time, and he's going to find an open receiver.
The third play is a touchdown throw by backup QB Clint Chelf.
Coach says the thing that stands out about this play is how much KU's defenders bite on the play-action fake.
Because the Jayhawks' safeties commit themselves to the run, OSU receiver Isaiah Anderson is left wide open in the end zone.
KU coach Turner Gill talks a lot about getting players to "fly to the ball" defensively.
This is an instance, Coach says, when that mind-set might be harmful to a defense.
"That’s what you teach your defense is create pursuit angles — flying to the ball; get there fast; get there aggressively," Coach says. "But you also have to be disciplined in your flying to the ball: Read your keys, and make sure you’ve got your eyes where they’re supposed to be on every given play."
