I'm not saying there is no validity in your points. It was without qualifiers but usage is usage based on whatever minutes you did play and 23% for a number 2 pick isn't that high at all if their sole reason for existing is based on production. Names above him include Shake Milton, Jordan Poole, and Boban Marjanovic. While I think Bagley going all weaksauce lately in the media is a bad idea, he has to be given credit for accepting his role as a spot big so Holmes could eat into the same space you would ideally want Bagley to be in. Holmes might always be better in that same space, but Bagley has been horrifically misused like many Kings bigs before him and it's one of the main reasons we should be completely bearish on a big like Sengun for the Kings. If they went with him so he can play behind Holmes and maybe even Harrell or at PF then they just likely increased the odds of another draft bust big even if he actually can play (See Papa G now). My goodness look at Hassan. Him getting away from this franchise when he did likely saved his career.
Again, the issue is how do you play Bagley at the 5 and expect the defense to Hold up? He did have some impressive games at the 5 offensively, but man is he lost when expected to be the lead rim protector. Gets cooked in the pnr, not good footwork to recover, not instinctual rim protector..
There's just too many issues. You can complain he gets misused, but the reality is he's been one of the worst regular rotation players in the NBA over his first 3 seasons. You can't blame all of that on "misuse". Doesn't really matter what metric you look at either, basically all of them grade him extremely poorly.
I wish him the best, but I think you hope some team still gives you value for him now and move on. This team has 2 franchise cornerstones locked in, the goal should be to find pieces that compliment and lift their game. Not fall victim to the sunk cost fallacy of a former #2 pick.
