At full strength the Clippers are like a Super Saiyan version of the Pelicans, inasmuch as they are strongest where the Kings are the weakest. Especially when Leonard plays: the Clippers are 7-3 in their last ten games versus the Kings when Leonard was available, and all three losses were one-possession games. Basically, if Leonard plays, the Kings have pretty much play perfectly to beat this team.
The Kings are not playing perfectly.
