as the two players are inevitably compared all offseason (assuming Keita signs, which looks encouraging).
Atiki averaged 14.7 points, 10.6 rebounds, 1.9 blocks, 9.0 fouls, Box Score +/- -2.1
Keita averaged 20.5 points, 13.3 rebounds, 2.7 blocks, 5.6 fouls, Box Score +/- +8.1
KenPom advanced stats
Atiki 102.3 ORtg, TS% 60.1, OR % 11.3, DR % 17.7, Assist Rate 4.9, TO Rate 24.6, Blk % 4.9, Stl % 1.6
Keita 116.6 ORtg, TS% 60.7, OR % 14.4, DR % 21.4, Assist Rate 7.3, TO Rate 13.1, Blk % 6.8, Stl % 2.9
There's not a single basic or advanced metric where AAA was more effective, and Keita is a year younger.
With the eyeball test Keita appears to have more coordination and more fluid movements, and I suspect a stronger defender particularly in switches where Keita might wind up on a guard.
I'm excited if we land him.
