I suppose it’s because slimeball coach John Calipari’s Memphis Tigers are having such a good year and playing some really good basketball, but is anyone else as tired of hearing about Memphis’s dribble-drive motion (DDM) offense as I am? It seems like that’s the hot item to chat about in the college basketball world this year, much as the Princeton offense was overexposed in years past. Sick of it yet?
Too bad. I’m going to talk about it some more. Specifically, I’m going to talk about what opponents have done to slow it down and what basketball god Bruce Pearl’s Vols can do to keep Memphis from scoring points in bunches.
The DDM is based on a really simple game: 1-on-1 basketball. The idea is that if you have superior athletes, particularly quick ones with the ability to finish at the rim, you can use their 1-on-1 skills to penetrate a defense repeatedly, creating easy opportunities near the bucket. At its core, the DDM is a triple option, to reference a common football term. Here is how it works:
- You utilize four perimeter/slashing players in the game at most times, leaving just one post player.
- The lone post player lines up away from the ball. If a guard has possession on the right-hand side of the key, the post player shifts to the left (weak) side in order to clear a path for dribble penetration, and vice versa. Most offenses do not line up this way.
- The perimeter player possessing the ball will attempt to beat his man off the dribble one-on-one. There are no screens and few cutters– initially there is just 1-on-1 at the perimeter.
- If he succeeds, he has the three options set up:
- Take the ball to the hole if there is no help defense.
- If the post defender leaves his man to help on the strong side, the penetrator can dish to the weak side, where his post player is uncovered.
- If another perimeter defender sags to help on the penetrator, he can kick the ball out for an open look at a 3-point jumper.
- If penetration is stopped without an open look, the attack simply begins again from the perimeter.
You can see that the key to the whole thing is having perimeter players that are skilled enough to beat their defenders 1-on-1. Memphis has that. Chris Douglas-Roberts is an excellent scorer both inside and outside, and Derrick Rose is quick and strong, creating major problems for his defender. The Tigers have depth at both of these positions as well as post players that can finish if the ball comes their way via pass or rebound.
So what is a defense to do? Can you possibly win enough 1-on-1 matchups against talented guards and wings to stop Memphis without help defense? No, of course not. You have to help somehow without freeing the lane or the wing.
Here is where the situation is not pretty for Tennessee. Man-to-man defense is going to be very, very difficult to play successfully against Memphis running the DDM offense, for one simple reason: when your defensive assignment is a man, you have to leave that man to help. As we all know, Bruce is very high on man defense and runs it almost exclusively.
So what do you do? Well, we can look at the games where Memphis has been slowed the most offensively for ideas. Here is a list of those games, what the opponent did, and the areas where Memphis struggled as a result:
- MTSU (away), 100.3 efficiency. The Blue Raiders switched defenses constantly, running a variety of zones and a small amount of man. As a result, Memphis turned the ball over and shot poorly.
- Houston (home), 96.7 efficiency. The Cougars also switched defenses frequently, running zones and man. Memphis shot very poorly.
- Tulsa (away), 94.9 efficiency. The Golden Hurricanes ran a couple of different zones as well as everyone’s favorite “junk” defense, the triangle and two (basically three interior defenders in a zone, with 2 dedicated man defenders). They managed to force Memphis into a bad shooting performance and also kept them off the line.
- UTEP (home), 92.8 efficiency. The Miners ran multiple zone looks, forcing Memphis into a low shooting percentage.
- Oklahoma (neutral), 86.8 efficiency. The Sooners ran mostly zone, forcing Memphis to shoot threes and turn the ball over in efforts to penetrate.
- Southern Cal (neutral), 76.8 efficiency. The Trojans ran a triangle and two on Douglas-Roberts and Rose nearly the entire game, with great success. The Tigers couldn’t get easy shots, couldn’t get to the line, and turned the ball over.
Notice any pattern? Zones and junk, zones and junk. None of the teams that played successful defense against the Tigers did it playing mostly man. They aren’t great from the perimeter (except CDR), so forcing them to stay outside as much as possible has been the optimal strategy. The best way to do that is with a zone, and clearly it works to some degree.
Bruce, Tony Jones, and game scout Jason Shay have some decisions to make. Do we use our bread and butter pressure man defense and hope we’re just better at it than anyone Memphis has played? Or do we stretch out of our comfort zone and sag into a zone defense, which seems to have been the winning (well, winninger) strategy for the Tigers’ previous opponents?
I suck at predictions so I’m not going to presume to know what we’ll do. I’d guess we’ll play mostly man, as we always do, but we may make an effort to throw the Tigers off with some junk or zone of our own a few times in the course of the game. If we do run mostly man, I’ll trust that Bruce has explored all options and decided that it is our best hope for a good defensive game. And maybe that’s correct– has Memphis played anyone that plays man defense in the manner and with the effectiveness that we do? Perhaps not. Perhaps we will succeed where others have failed.
