I don't think it was a mistake & believe those jerseys have a place in the rafters.
Personally, having watched all those game, the majority from the lower arena at Rupp, I believe the story is where those guys started & where they ascended to & took the program. Those guys sat on the end of the bench to begin their careers. For all intents & purposes they looked like they would be nothing more than "human victory cigars" during their career.
From there, the work they put in under RP & Rock Oliver transformed them into key contributors on a NC contender & brought this program back from the depths much, much quickly, in my opinion, than would've ever happened otherwise. They stuck around, when others were either leaving, or not coming.
Say what you want about my opinion, and you certainly might disagree with me. And that's ok, but I was there, and I will never forget what that team did & what meant they to the program.
