We arguably have 2 (legitimate) rotational forwards in Grant and Nas, kinda depends on how you feel about Nas/Winslow. Given Nas injury history and I think Winslow is meh, you could argue we have 1 legitimate rotational forward in Grant.
Don't come at me with Josh Hart. He's a SG, who is going to be forced to play out of position.
We have about 4(ish) rotational guards.
Dame
Ant
Hart
GP2
Sharpe is a question mark.
We have 1 decent center.
So the spot with the most rotational depth also has:
Didi
Keon
Bledsoe (as of now)
For a total of 8 (over half the roster) spots, while we are sorely lacking in wing (starting and bench) and backup PF/C talent.
Removing GP2 for Otto Porter Jr, TJ Warren or even Jalen Smith would've been a much more sensible play.
