Couldn't agree more. I really have no preference, I just want Duke to win, and win in any way possible. You are exactly right to point out that saying freshman dominated teams don't win titles is inaccurate.
IMO there have been 2 programs with freshman dominated teams (Duke and UK) and the fact that both programs won a title this decade with those teams is pretty remarkable. Sure, 8 other titles this decade were won with upperclassman, of course there was, because every other program in America is trying to win that way.
It drives me crazy when folks complain about the 2018 and 2019 Duke teams. I know we came up short, and I know we had all the talent in the world. But those teams had a CHANCE to win the title, and in college basketball that's all you can hope for. The older teams of 07-09 had 0 chance. Same with 2012 and 2014, which weren't young teams.
