This is what we should keep in mind: what has many of us excited about this offseason so far isn't necessarily that we've gotten "older," but rather that we've created continuity. In all likelihood 3 of our 5 starters next season will be returners from last year. Our sixth man (Maliq) will be a returner as well, and there's a real chance another returner (Darren) will earn a sharpshooter-off-the-bench role.
Miya has shown that each of the national champions in the portal era has had returners account for >50% of the team's minutes played. Last year in the final four we were a crazy outlier in only having ~25% of our minutes played by returners (mostly Tyrese, supplemented by Caleb)... the other teams were in the 70-80% range. You can get "old" in the portal, but you can't get the continuity that we'll have from returning 5 scholarship guys.
