You mean where he led the league in rebounds, that summer league? He was the focal point of the offense there and would be the 5th option offensively in the regular season. He showed he can bang inside, which is what he'd be asked to do.
And taking a look at him briefly as a backup in certain situations is NOT gifting him minutes he didn't earn. If Monty plays him, he earned that time. YOU know much less than Monty and NEVER seen Jalen practice or have any insight into whether he's earned minutes or not. I know you want him glued to the bench until he magically becomes a starter but that doesn't happen without reps. Getting him some reps against certain teams in various situations is for the best
Absolutely no one is calling for him to receive big minutes or to play a consistent role of any sort of importance. So quit trying to push some false narrative that people here are demanding he be used as a key player.
I know that practice (where Dragan Bender once reportedly looked like the next coming of Dirk Nowitzki) doesn't say diddly squat about ability in actual games.
And I HAVE seen Jalen Smith play in actual games...every Summer League game in which he played most recently, and to put it bluntly he was the most awkward and least coordinated basketball player I have ever seen. He literally couldn't control his body for so much as a single step. His body appeared to be an amalgam of mismatched parts. Yes, he grabbed a ton of rebounds on a team that laid enough bricks to build a large city, but while he got a number of rebounds that bounced right to him, he more often let balls slip right through his fingers, and he very rarely came down with contested rebounds. He didn't block, or really even contest, shots. He repeatedly missed layups (where he got a number of his rebounds). He threw the ball away a lot. He had poor handles. He shot and missed a ton of threes.
He hasn't earned a minute of NBA playing time. Not. One. Minute. Advocating him getting so much as a single rep in a real NBA game other than purely in garbage time is advocating for a return to the losing philosophy and culture under McD where players like Chriss and Bender played real NBA minutes before earning them, only this time would be even worse, because this time the team is supposed to be a championship contender, and unlike Chriss and Bender, Jalen Smith has yet to prove he can even be a positive contributor in Summer League or the G League.
You're the one pushing the false narrative here. Jalen Smith needs to be in the G League until he at least can prove he can cut it at that level.
