Anderson would play the three and Kawhi would play the two. Kyle would get the worse wing to guard. He seems like a decent corner shooter now, so he can spot up there at the worst. The rebounding would be insane with Kyle, Leonard, LMA and Duncan. And there'd be nice help defense. I don't think it's a playoff-worthy lineup, but I wouldn't mind rolling it out against the majority of opponents.
And it's not like Danny wouldn't still be playing starter's minutes. He'd probably come in at the seven- or eight-minute mark and close out the quarter. Then he'd come back at the nine-minute mark of the second and play until the two- or three-minute mark. It would mean Kawhi wouldn't play as deep into the first, but that's probably a good thing anyway.
