After watching both preseason games, RJ has got it. It behooves both the team and him to have RJ situated with the big boys more often than the Red Claws this season. He has earned it early on.
Couldn't care less about SL stats here. He has already proven that: a) he has a BBIQ well beyond his years, b) isn't rattled by the big stage despite his status, c) has a certifiable NBA skill, and d) fills a major void for us as a knock down shooter WHILE ALSO showing he can contribute in many other ways. The major question mark of how he can handle NBA 2-3s defensively is obviously still unanswered, but if he can carry his weight defensively, then the young man just looks the part ... works without the need for explanation, much like Kelly's "bun."
I am hopeful for Rozier and believe the D League will benefit he, Mickey, and (not) Young this season, but would argue that sending RJ down isn't going to help his growth beyond building confidence, which he seems to already have. He's too heady to send off to get reps for that purpose alone, especially if he doesn't need it. And what natural/physical defensive deficiencies he has seem like they could be countered by his length, effort, and BBIQ. He's proven, by my 20/10 eye test, to be NBA-caliber already, and primed to be a Celtic beyond his rookie contract. Very comfortable making that my bold prediction for the future.
