Why can’t Chet Holmgren punish small guards and wings in the post?

Chet should’ve scored at will over Julian Champaignie and Devin Vassell when they were matched onto him. I’d give him a pass if he’s not able to take advantage against huge wings or forwards like Keldon Johnson, OG Anunoby, Scottie Barnes, Julius Randle, Aaron Gordon, or Giannis.

However, he gets no free pass whatsoever by not scoring over any of the players the Spurs put on him. If he can’t score against those guys, he probably wont be able to score on guys like Jose Alvarado, James Harden, Steph Curry, Trae Young, or Jalen Brunson if they get put on him. Teams will be able to hide their weakest defender on Chet since he can’t take advantage of any mismatches in the post
