Eh. Good? That's a stretch.
Rozier might be, I don't know, a poor man's Dennis Schroder or Reggie Jackson. Cool. That's another minor "asset," though it doesn't really do anything for the team. No clear path to playing time, which is necessary if a guy is going to develop in a meaningful way.
RJ Hunter might be Anthony Morrow or he might be Elliot Williams. Guys like that are available in free agency every year.
Mickey is probably not an NBA rotation player. Best case, he's a guy you throw in for a few minutes here and there to grab rebounds and block shots. He doesn't help the team in terms of size inside or in terms of scoring ability. No clear path to a larger role on the team.
MTWD (Marcus Thornton with Dreads), will be in the D-League or Russia next year, and probably for most of his career. Cool.
