Clippers are easily the deepest team in the NBA.
For me the big question for them (besides health) is chemistry/lineups. They have no real two-way center or point guard and some of their best offensive lineups create defensive holes. They still need to figure out what their ideal playoff lineup is and what their identity is when Kawhi and to a lesser extent PG13 are off the floor.
It wasn't as much a lack of chemistry imo as it was their complimentary pieces were trash before the upgrades.
Prior to RJ and Morris, their bench was overrated (too much iso and gave up as many points as they scored) and it didn't matter who KL/PG guards if a team will just force the switch to the weakest link (Lou or Shamet) to close games.
But now RJ moves Lou to the 2 guard (no more facilitator role + easier to hide on defense) and Bev-PG-KL-Morris-Trez is their best and no brainer (closing) lineup if Doc has any sense. He may be too loyal to Lou tho, so I think their end of game identity is a big question mark.
