Interesting analysis of some of the line ups. The Celtics won by 3 points. Here is how the various combinations of Horford and Grant did:
Horford + Grant -8 / 25 min
Horford, No Grant +1 / 7 min
Grant, No Horford +14 / 13 min
No Grant or Horford -4 / 3 min
Grant took zero shots, made 2 FTs, got 5 rebs but somehow ended up producing a really good +/- results for the team. On the season, Grant + Horford is +6 in 74 min. Maybe just one bad game or a statistical anomaly?
I think this game was poor with that combo because it was Grant + Horford against the opposition starting unit (thankfully without Adams). Typically, Grant and Al would be playing against other lineups partially made up of bench players.
Not sure what it is, but Grant seems to freeze up when he's in the starting lineup
Grants biggest strength (by a wide margin) is his 3pt shooting ability. It’s the only thing he does at a high level. So if he’s a 5th option out there with the starters, that’s not really a great benefit to the team. Rob and Al with their rebounding, rim protection, and passing abilities make them better complimentary players. Grant is more effective off the bench where he is able to get more looks on offense.
Especially off the driving and kicking of Brogdon
There is some correlation between Grant and Brogdon. This game, they were +8 together but that is a season long trend:
Grant with Brogdon +55/157 min
Grant no Brogdon -19/83 min
Brogdon no Grant -25/81 min
The team seems to benefit when both are on the floor together, and by a fairly clear differential. At least through 10 games, a small but not insignificant sample size.
This lines up with the eye test and makes it clear that Brogdon and Grant should be used off the bench and mostly together. It is also interesting that Brogdon and Grant with starters is a good line up (with Smart, Brown, Tatum, +10 in 11 min), albeit very limited minutes. Swap in Horford for Grant with that line up and it is -28 in 29 min. Still not a lot of minutes but supports the correlation that Brogdon and Grant are complementary.
If you look at it individually, it is also a bit strange. These are all the players with more than 200 minutes.
Grant Williams +36
Malcolm Brogdon +30
Jayson Tatum +29
Derrick White +25
Al Horford -16
Jaylen Brown -18
Marcus Smart -34
