If we could get to the E8 or F4 once every 4 or 5 years, that would be taking us to the next level in my opinion.
I've been thinking about this sentence all day. Specifically: How many teams are there that get to the Elite 8 every 5 years or so, and maybe the Final Four every 10?
So, I ran the numbers on the last 10 NCAAs. There were 18 teams that got to at least 1 FF and 2 EEs:
Villlanova (3 FFs, 3 EEs)
North Carolina (3 FFs, 3 EEs)
Gonzaga (2 FFs, 5 EEs)
Duke (2 FFs, 5 EEs)
Michigan (2 FFs, 4 EEs)
Kentucky (2 FFs, 4 EEs)
Kansas (2 FFs, 4 EEs)
Michigan State (2 FFs, 3 EEs)
Wisconsin (2 FFs, 2 EEs)
UConn (2 FFs, 2 EEs)
Syracuse (2 FFs, 2 EEs)
Florida (1 FFs, 3 EEs)
Virginia (1 FFs, 2 EEs)
Texas Tech (1 FFs, 2 EEs)
Oregon (1 FFs, 2 EEs)
Miami (FL) (1 FFs, 2 EEs)
Louisville (1 FFs, 2 EEs)
Houston (1 FFs, 2 EEs)
Based on that, I'd say it's a reasonable long-term metric to aim for.
