Kawhi used 22 possessions a game compared to LMA's 24. Either way, acting like Kawhi being the "second option" matters is silly, seeing as people have been ing for two years about LMA despite him being the second option now.
Aldridge also had the highest rebound rate on the team excepting Boban who almost exclusively played in garbage time. He wasn't the problem on the boards -- literally everyone else in the big rotation was. No other big besides LMA was even on the team the next season, to put into perspective what he had to work with.
