Some of this is on Pop tbh. They seldom ever ran P&R together, instead it was Kawhi and Pau with LMA spotting up in the left corner. Kawhi would either pullup, drive, or pass back to Gasol for an open 3, Aldridge would pretty much be left out of the play.
If Kawhi is back next season, I hope that Pop continues to start LMA at center with Murray, Green, Leonard, Bertans and filling out the starting lineup. LMA would be the primary screener for Kawhi with Bertans and Green helping to space the floor on those possessions. During LA's post ups, Leonard, Bertans and Green can space the floor. The Spurs have better much better offensively and fairly even defensively with LMA at center as opposed to Aldridge and Gasol units that would figure to be much better if Kawhi is healthy.
Leonard does need to do a better job of seeking Aldridge out and stop resorting to Kawhiso's as much. They should be able to help each other gain mismatches; LMA pulls the opposing big away from the rim ( Bertans would do the same with the other one) teams generally wouldn't be able to switch the p&r or risk having Kawhi being guarded by a 4 or 5 and Aldridge by a 3 leading to a miss match on the perimeter and in the post.
