NBA Statistics: Looking at the Utah Jazz defense over the last four years in Synergy
By AllThatAmar
Was this a fast break, or a defensive breakdown? - Ronald Martinez
I'm not joking you right now. (I see ya, Jimbo) The Utah Jazz are not that great on defense. Particularly not since the NBA has changed the rules to give even more advantages to quick guys who can penetrate. (I see ya, Moni #UDQM) Back when we could play a soft-ish zone with a Mark Eaton or Greg Ostertag anchoring things in the middle while we could be a little 'grabbier' on the perimeter things were fine. Things are different now. And since we've had access to Synergy we've isolated some of our problems (in the stats world) to things that match up with the eye-ball test: isolation defense, pick and roll defense, and spot up defense.
When there is an isolation the defender is mostly on an island right now, and if you actually are a team with a team defensive concept (and not every team does) then your man who is used to playing team defense is all alone. The Pick and Roll is something we should know pretty well, either you get the screen setter a great shot, or the ball handler is free to go nuts on us. And in all cases, depending on the defensive over-reaction in rotating (or not rotating at all) -- there could be one or more opponents left wide open for spot up shots. To wit, this is what we were picked apart by in the playoffs against the San Antonio Spurs two seasons ago. We had trouble with dribble penetration (via isolations or pick and rolls), and our defensive system would not work in relation to this external threat (essentially a biological cell without a cell membrane), and we'd leave people wide open.
Effectively, it's these simple defensive fundamentals that unravels us completely. I think, to our defense, this is what happens to most teams as well. But on a young team with a coach who is inexperienced as well -- and bad defenders hogging up the majority of the minutes -- we had some poor results.
Let's look at the changes over time, from the last four seasons across the Synergy stats for our defense overall, in isolations, on pick and rolls, and against spot ups. And yes, it's the middle of July and SLC Dunk is going back to summer school already looking at our team. Our blog (and a big part are the participants in the comments section) kicks so much butt that you guys motivate me to write so much all year long. (No RV vacation for the AllThatFamily this year)

For the four years our overall defense, as a product of PPP, ranks at 18.0th best in the NBA. That's nice. It's also in the bottom half of the league. We kinda knew that already. The other team shot a cumulative 45.6 fg% against us, and made 2,226 threes against us at a 36.0 3pt% clip. There were significant areas where we could have improved -- but over all we're "middle-ish" of the pack defensively. The trend overall was a downward trend in defensive rank, while our PPP got lower (which is better for defense). Our W/L record started to look better as well, but we were far and away removed from the 09-10 season when we were a playoff contender (small "c", not big "C") and we played a different type of game and our offense worked.
We look at our defense overall as the baseline with which to judge how good or bad we are at the different parts / defending different plays. I will say that fixing the defense is a long term project, it's not something that changes over night. And while or defense was quite poor in 2010-11, I think we're in the middle of fixing things. With better talent on the floor, and a more unified defensive system I think that NEXT season (2013-14) we could have a Top 15 defense in the league. Baby steps.

Okay, well, we're not that bad here. Over the four year period guys only shot 39.3 fg% against us in isolation, and shot under 30 3pt%. That's not bad. This data doesn't show how frequently a guy got to the line against us (an oversight in displaying this information here -- but still calculated in the PPP values), but it does show us that we faced isolations about 11 times a game, and each year the value went down. This could be a product of our pace going down as well. But when we faced them, we did not suck.
We were really bad at this for two seasons, but last year we made a come back. I think part of this has to deal with guys thinking they can score one on one against Gordon Hayward. They under-estimate him, and learn the hard way. More seriously, in isolations the Jazz don't usually send a help defender over. Which is fine now. But for the middle two seasons this meant "we did not send a help defender over, because the primary defender wasn't playing defense either." Yeah, I'm a mean guy. Get over it. But as bad or improved our defense is here, this isn't the main reason for panic.

Glossary:
- G = games, this includes lock out shortened seasons and playoff extended seasons. It's not 82 games for each set
- # = number of defensive possessions
- PPP = points per possession
- NBA Rank = league-wide rank in terms of defensive ability in terms of PPP (lower is better here), there are 30 NBA teams
- # / Game = number of defensive possessions per game
- ePPG = estimated points per game, for a particular defensive play type
- paPPG = pace adjusted points per game, adjusted to 100 possessions
- Yes, the last three things are data points that MySynergySports.com doesn't even display, I calculated it myself because you SLC Dunk readers are smart enough and deserve the best information all year long.
