One of these threads has actual numbers when Monk is playing with the projected starters and the Kings are in the red per 100 possessions with Monk while they are in the black with Keon. I think it's somewhere between a 7-10 point differential while also being the difference between a positive and negative +/- when Keon is with the starters vs Monk. I don't know how to find these splits and a quick google didn't find them either. Hopefully whoever posted them originally can share.
it’s the Huerter numbers that were surprisingly better, to me.
