Both young cores seem to be similar, with a lead superstar guard, a 2-way guard/forward, and a floor-spacing rim protector. The Grizzlies’ core have had more playoff success (due to being around longer) and JJJ also already has a DPOY, but they’ve also got more potential concerns (namely Ja’s off-court behavior and some of JJJ’s struggles like rebounding)
I don’t think what you said is biased at all and I definitely agree both could be better than their Memphis counterparts.
