Pretty clear the team has been best with Jaylen Brown out there. But some indication that they're better with Smart out there as well than without.
But to be fair -- the minutes without Smart are probably mostly against starters while the minutes with Smart are probably against at least partial bench lineups.
Kemba and Smart had to play 3 games without Brown and his replacements were awful.
The sample sizes are very small, of course, but here is the purest Brown | Smart swap within the starting lineups (made possible by virtue of Brown missing 3 games):
Kemba+Smart+Gordon+Jayson+Theis 50 minutes, 103.8 ORtg, 89.2 DRtg, +14.6
Kemba+Brown+Gordon+Jayson+Theis 27 minutes, 120.0 ORtg, 86.7 DRtg, +33.3
Of course, Gordon got hurt and now we have
Kemba+Smart+Brown+Jayson+Theis. 21 minutes, 140.5 ORtg, 76.7 DRtg, +63.7
To be fair, that last lineup was against arguably the weakest competition. And of course right now, THEIS has gotten hurt!!! Argh!
Small samples are small. Don't read too much into any of this.
Would really like to see this team fully healthy when the playoffs come around!
