cleaningtheglass.com has the Cavs better defensively by 9.4 points per 100 possessions when Strus is on the floor and also 9.4 points better with Mitchell. Wade is next best at 9.3 followed by Mobley at 8.9. All of them are in the 92nd to 94th percentile among players at their positions.
After those four there's a dropoff to Okoro at 5.3 (80th percentile among wings) and then Garland at 1.0. Surprisingly, the Cavs are only 0.4 points better defensively with Allen on the floor.
When we have a solid lead in the 4th quarter and want to shut the opponent down I recommend a unit of Mitchell, Strus, Okoro, Wade, and Mobley.
Actually, that lineup has been on the floor for 36 possessions this year and they got killed, allowing 36 more points than they scored per 100 possessions. Small sample, of course, but they've been awful offensively, scoring just 64 points per 100 possessions. You can't put Okoro and Wade on the floor together.
Our best defensive lineup, among those on the floor for more than 20 possessions, has been Garland, Mitchell, Strus, LeVert, and Mobley, which is surprising because LeVert does not have a good defensive rating and Garland is neutral. But that lineup is scoring 130 points and allowing 76 points per 100 possessions. It has been the "death lineup" for opponents. Five guys who can all score and three of them are in the top 8% at their positions in defensive on/off. That unit has been on the floor for 54 possessions, or a little over one half. Not a big sample, but I'd like to see more.
The group that really does well together is Mitchell, Strus, LeVert, and Mobley. Put Niang with that foursome and they outscore opponents by 29.4 points. Put in Allen instead of Niang and it's 28.7 points. Put in Wade and it's 12.3. The only fifth wheel that doesn't work is Okoro at -13.5.
One of the keys of basketball coaching is to find the combination of players that fit best together so the whole is greater than the sum of the parts. In an NBA season you have 82 games to accomplish that. I'll keep an eye on these units going forward and see which ones emerge as the most effective.
