I agree except about RJ. He legitimately got a shot to be a major piece as a sophomore but he just didn't improve at all.
Since then I think Brad is treating unproven players as basically we're going to continue to bring in talent and you're going to have to earn it.
But whether it's Hansberry or a guy like RJ who didn't really take his opportunity you COULD say "we are betting on you, we are paying you as the player we believe you can be, we are going to forego other options to keep believing and grinding with the kids we recruited".
There are programs attempting some flavor of that. Certainly moreso than us. If the schools that prioritize stability show more player development and more cohesiveness and consistently win games against the portal rent-a-teams everybody is going to start bending toward that strategy.
Early returns kinda look like the opposite though (look at us and Michigan State this year for example). Just spend your NIL dollars on the best new team you can find every year. But it's early.
My point is, it's not IMPOSSIBLE to keep a team together, at least to a significant degree, especially if you're NIL rich like us. We CAN achieve that if we want to. It would just mean foregoing proven quality for potential quality, which BU is understandably unwilling to do based on the data we have.
