Here are all the 5-man units that we played at least 20 minutes as of Game 53 (the first game with the complete final roster, including Isaiah, JJ & Luigi) and their offensive, defensive & net rating (points surrendered per 100). For the sake of this thread's discussion, they are sorted by defensive rating.
Some of the results may run counter to what some of you believe about some of our players:
5-man-unit minutes ORtg DRtg NetRtg
1. MS+AB+ET+JC+TZ 21.0 124.4 87.5 +36.9
2. IT+MS+JC+JJ+KO 26.3 124.5 90.2 +34.3
3. IT+AB+ET+BB+TZ 30.1 121.1 93.2 +27.8
4. MS+ET+JC+BB+TZ 31.7 110.2 101.8 + 8.4
5. IT+AB+ET+JC+TZ 41.0 104.5 103.7 + 0.8

7. MS+AB+ET+BB+TZ 271.3 97.2 104.4 - 7.2

11. MS+AB+ET+JC+BB 29.4 127.0 142.1 -15.1
Unfortunately, the sample sizes are small for several of these lineups. And definitely way too high for one of them (if you look at the ORtgs, you should understand why I say that).
Still, if you look closely, you can find some interesting bits of information here.
Only two of the lineups posted a negative NetRtg. Neither of those had IT4 on it.
Marcus Smart was on our best defensive lineup (albeit with the tiniest sample size) and also on our worst defensive lineup.
In fact, the only difference between our best defensive lineup and our worst was swapping Zeller for Bass.
Zeller was the center on 6 of our 8 best defensive lineups and all 8 had a 7 footer, either Tyler or KO at center. Our two worst defensive lineups (by a huge margin) both had Bass as the center.
With the exception of the aforementioned 'best' lineup that was only 21 minutes for Marcus, swapping Isaiah in for Marcus did NOT, surprisingly result in worse defense. The opposite, in fact. In particular, note lineup pairs (10 & 11) and (3 & 7).
Isaiah and Marcus were each on 3 of the 5 best defensive lineups, including one that had both of them on it.
Overall, one can't help but wonder why we gave such a huge portion of minutes to lineup #7 (the starters) when it was one of the only combinations that was clearly NOT working.
