If you are talking about leaping ability, then maybe they are not comparable but let's not forget: TRoz was a 3-star recruit who averaged 7 ppg as a freshman and then had a great sophomore year before declaring for the draft. He also had a terrible rookie year and a not great second year (as discussed above) though showing flashes. He was also healthy the entire time.
Romeo was a five-star recruit, the #1 rated guard by ESPN in his class, and averaged 16.5 ppg in his freshman year with a torn ligament in his wrist. He was also, IIRC, in the 90th percentile in Pick n' Roll plays on a IND team that wasn't all that good. His first NBA year, he had to recover from wrist surgery and other injuries plus had to deal with the stoppage of the league.
If we could get DA and CBS under truth serum, my guess is that they have no doubt that as long as he stays healthy, Romeo will be able to score in the NBA. I mean if Romeo was on OKC, he'd probably be scoring in double digits a game. He just hasn't had the opportunities.
And before anyone brings up work ethic, from the little we've heard, Romeo works as hard as anyone.
