There's lots of things in sports that need to be re-examined.

Overtime in the NFL. The college bowl season. The NBA and NHL regular seasons. The WNBA as a whole.

One things in sports that is perfect as is is the NCAA Men's Basketball Tournament, or as I like to call it, "Three Weeks of Heaven."

That could change, though, as NCAA officials have had preliminary discussions about expanding the tournament - currently at 65 teams - to 96 teams. The only motivating factor that could lead to this coming to fruition is cash money.

Revenue drives everything, and the Big Dance is no different. However, there never seems to be a shortage of advertisers when March Madness rolls around each year. Add that to the fact the tournament is a perfect Made for TV event - four games on at once, 12 straight hours of coverage over the first two days, constant updates during games, CBS cutting away from games when others are tight down the stretch - and there is absolutely no need to mess with such a good thing. That'd be like Jessica Alba or Zoe Saldana feeling the need to get breast implants.

This could be a knee-jerk reaction to the low ratings drawn by the 2009 National Championship game between North Carolina and Michigan State, which saw a 7-percent decrease in viewers, according to a report published shortly after last year's title game. That was offset, though, by a 5-percent increase in viewership for the entire tournament.

College basketball, for the most part, has been the one sport that has stayed true to players and fans. There's no TV break every couple minutes. There's rarely an extended commercial break during a game. And the sport, in general, is fun. Expanding the field of the tournament would take from that, and, for what? To make a few extra dollars? Granted, it'd be much more than that, but adding 31 teams to the Dance would kill competition across the board.

That expansion would turn March Madness into essentially the college bowl season, where even the most mediocre team would have a shot (albeit not a realistic one) to win a national title. Bowl games are different, though. You have a 6-6 team that gets a trip to Mobile, Ala., to play in what really accounts as a meaningless game. Unlike bowl season and its several Toilet Bowls, there are no meaningless games in the NCAA Tournament. All 63 contests are a part of a story.

That story should continue to have only the best teams as characters. During bowl season, which I do love, by the way, about 60 percent of Football Bowl Subdivision Teams get a payday. Only 19 percent of D-I men's basketball teams (347 total) make the Big Dance. That means only the cream of the crop are invited.

Take Connecticut for example. UCONN advanced to the Final Four as a one seed last year. This year, after some attrition, coach Jim Calhoun's temporary leave of absence and some admittedly bad play, UCONN finished the season 17-15, 7-11 in the tough Big East. The Huskies had 15 chances to beat potential Tourney teams and made good on just three of those. But, with an expanded tournament field, UCONN would, more than likely, be a shoo-in to make the tournament with that barely above .500 record.

What sense does that make? Why would any team schedule tough non-conference opponents or go on the the road in the non-conference when it knows it can have an up-and-down year, finish in the middle - or near the bottom- of its conference and still have a shot at the national title? What would be the purpose of conference tournaments (other than, yea, you guessed it, money)?

Why would anyone get excited about Championship Week and Selection Sunday? Why would I take the first two days of the tournament off every year to watch 15-15 Michigan play 16-14 North Carolina State when neither team has a shot to make any noise? Isn't that what the NIT is for? Or would the expansion serve as a way to do away with the NIT, as some have speculated, since Three Weeks of Heaven may move from CBS to ESPN, which currently broadcasts the NIT?

And what would become of the mid- and low-major conferences? Schools like Dayton and UTEP don't generate a whole hell of a lot of revenue, but it's schools like those and others who are a part of the charm of the tournament. Gonzaga, Davidson, George Mason, Bucknell, Howard and others are the schools that really make March Mad.

Could a team like, say, Arizona State, really be considered a "Cinderella" when it's on a level playing field revenue- and recruiting-wise with the likes of UCLA and Washington? I don't think so. But if the tournament field is expanded. I can't help but believe the move would be made in part to make room for more power conference (Big Ten, SEC, Big East, ACC, Pac 10, Big 12) teams.

If there is real talk of expanding Three Weeks of Heaven, it should stop. Now. As the saying goes, "If it ain't broke, don't try to fix it." The NCAA tournament doesn't need tweaking. It's perfect the way it is.

Now if you'll excuse me, I'm gonna check TMZ.com to make sure Jessica Alba hasn't done anything stupid.
