Small sample size theater is all over this one, but it’s also in line with Wallace’s career arc and wisdom about his game: he’s excellent attacking the rim and finding little cuts in the defense, doesn’t shoot much (or well) from midrange, and is best shooting long-range shots from the corner.
This chart is similar to Gerald Wallace’s shot chart last year — he was active and effective attacking the rim, but limited his midrange jumper and wasn’t particularly effective shooting threes.
