From a distance, seems like Knox didnt make waves the way Trier did, playing large parts of the game with blinders on. My guess would be that its more about where their respective games are, than it is about draft order. How they got signed.
If you watched Knox this season, you would have seen a player who needed a lot of work on offense. His takes to the rim were the best illustration of the need for reps.
Trier offensively looked like he was much further along. Look at his fg pct. Knox needed the reps to get to the next level. In some ways Trier was already there. He could afford to be more of a distributor. Guessing his teammates noticed this as well, and didnt appreciate Tier's ball stopping.
