Ok so, I see your points. But playing a few mins here and there and not having the ball in your hands or being involved, is very different than what you’re referring to.
Neither have had much of opportunity TO develop in an actual game setting. They don’t get sets ran for them like the big 3 do. If you have ever played organized basketball, practice and games are completely different. It’s tough to keep your confidence/get your in game skills up, if you dont have the ball as much as others.
They very well may have some skills that you don’t think they have but you also don’t know if they are told to only do certain things in games.
For example, last year, Myles role was to come off the bench and hit the open 3 if it was there. If it wasn’t, get the ball to Zach. He wasn’t asked to do much more.
