They also have little depth. They need any semi-talented warm bodies at this point. Obviously a great player like KD will help.
But remember circumstances can play into numbers as well. Same reason coming into the Finals they were 6-4 with KD and 6-0 without him in the playoffs. Circumstances.
With a healthy Iggy and Klay they matchup with Toronto OK. With either of them injured and KD injured they really, really struggle defensively.
