I'd be a lot more troubled by the lack of assists, except none of these guys are handling the ball and initiating the offense a ton. Simons has been playing the 2, Trent the 3 and Layman the 4. Baldwin is doing most of the ballhandling and getting these guys the ball in position to take makeable shots.
If they were taking a ton of bad shots and missing open people, I'd be more concerned, but that hasn't been the case from what I've seen. And two of these guys are 19-year-olds and the other is a stretch-4.
If this is the worst things to take away from summer league, we all should be thrilled.
