Here's my idea for the NCAA Tournament.
Select 8 cities that host the games. They host every year BUT they use different venues for the stages in the tournament. Here would be the cities. This would be in 2012 (when the tournament has nothing scheduled), and they must have 3 venues that can be used for the tourney. They would use one (or two if no Final 4 stadium) for the pre-Sweet 16, one for the regional, and one for the Final 4 with exceptions.
Indianapolis-(Lucas Oil Stadium, Conseco Fieldhouse, Hinkle Fieldhouse). Hinkle is the greatest sports venue in the world. It's a shame it doesn't host anything. Conseco is perfect in every possible way. Lucas Oil will be a great place to have basketball with the new set up. Indianapolis has to have games because it's the home of the NCAA.
New York Region-(Madison Square Garden, Barclays Center, Prudential Center). No Final 4 would be played here, but they will have 3 quality arenas that give the tourney an East Coast look.
Philadelphia-(Wachovia Center, Wachovia Spectrum, Palestra). Two new arenas and one of the most historic college basketball courts in America.
Miami-(New Marlins Stadium, American Airlines Arena, Miami Arena). Give the tournament a Final 4 in the South plus two more big arenas.
Detroit-(Ford Field, Palace of Auburn Hills, Joe Louis Arena). Final 4 in Ford Field and two medium size arenas.
Phoenix Region-(U of Phoenix Stadium, US Airways Center, Chase Field). Biggest arenas. Two places that a Final 4 could be held at.
Atlanta-(Georgia Dome, Phillips Arena, Gwinett Center). Has 3 capable stadiums. Not many cities have that now.
Southern California-(Staples Center, Honda Center, Cox Arena). Meh. Big city needs some big events.
Atlanta, Phoenix, Detroit, Miami, and Indianapolis could all have a Final 4. This could provide more stability to the tournament and make it easier for people to buy tickets. This would have 2 teams in the Northeast-Atlantic region (New York, Philadelphia), 2 in the South (Miami, Atlanta), 2 in the Midwest (Detroit, Indianapolis), and 2 in the West (Los Angeles, Phoenix).
