Early seedings seem like a pointless thing: the committee wanting to make itself useful for more than just March, maybe.
With UConn on the outside looking in (with respect to conferences), and given how much enthusiasm surrounds marquee OOC matchups in February, I would like to wave a magic wand and accomplish the following:
1. A mandatory rearranging of conference schedules. All conference schedules start in early-mid December. Then, there's a two week period in February in which conference games cannot take place.
2. Here's where the committee can make itself useful. Have them rank the teams using a mixture of polls, previous year results, and eye test. The number 1 team plays the next four teams down (not including any conference teams within that block). The number 2 team plays the number 1 team, plus the next three teams down. And so forth, all the way down to the 10th or even 20th rank. Try to set it up so that most or all teams get two home and two away games.
The main drawback? There would probably be more interesting matchups in all of that than there would be in the NCAA tournament itself.
