1. We need deeper bench and probably the willingness of BF to play more players, not just 7-8 players.
2. More "athletic" or "physical" players. Judging on how the game has evolved and how the games are called, it seems a lot of times that we are less physical.
You also need to take into account that recruiting WBB players is different from recruiting MBB players. The goal for most of MBB players is to go pro, not education. For WBB players, the primary goal will be education. It'll be hard to compete against Stanford, Cal, USC, etc.
The landscape is also different: if a MBB player wants to transfer, there's a lot of GOOD programs that will take him instantly. It's not the case with a WBB player. A lot of WBB players choose the "safe" or less risky choice.
The rest depends on luck to get to Final 4.
So we're fighting on different fronts here: location, educational reputation, system, etc.
Not that it can't be done. The stars need to align correctly to make this happen.
