As Blazers, Crabbe played too introverted, and Barton too extroverted. Crabbe depended on the playmaker's pass before his catch-and-shoot. Barton dribbled aimlessly looking to pass like a playmaker. Under their new coaches, they may have changed; I don't know.
We all hope that Trent will combine the best, not worst, traits of those two. Olshey drafted him as a 1-dimensional shooter. So in Summer League, Trent was told to brainlessly shoot with no hesitation or conscience. He dribbled thundering down the court, knowing in advance that he would pull up and shoot without looking to pass, and missed most.
Maybe Olshey told coaches to develop Trent this season in this order: 1) Remove any Crabbe-like overthinking, 2) polish off any Barton-like goofiness. In Summer League, we saw 1).
