I don't. The Helms and any mythical National Championship (Coach's Poll, AP, UPI) are never better than a tournament. A 68-team tournament is better than a 8-team tournament. My point is that how much better is an 8-Team Tournament than a mythical championship? A step or two maybe but not heads and tails. The modern tournament started in 1984 when it expanded to 64+ teams.
But I could make a case that the best team in 1953-54 wasn't LaSalle, the NCAA Tournament winner but it was Kentucky, the 1953-54 Helms Champions who didn't go to the Tournament. And, I know that you know that those decisions were not made by 'marketing guy' but a committee of sports executives and sports media.
Sometimes hindsight has a better view.
Ahh, but how many times does the best team actually win the tournament? Yet those that do are the champs regardless.
