Herro's averaging 31.6 minutes per game.  If he's only playing against scrubs, and each game is 48 minutes long, that means the starters of teams Tyler is playing against are only playing 16.4 minutes per game.  Charles, as always, oversimplifies.  Even if we were to assume every starter played 32 minutes a night, that would only leave 16 minutes a night (out of almost 32 minutes) where he was able to play against reserves.
Tyler is playing starters minutes, and honestly more than half of those minutes are against starters.  Most teams stagger their lineups.
The only valid point Charles makes, and it is valid, is that Trae and Doncic have to carry their respective teams and Tyler really doesn't...
