Here is a bit more on the idea:

From the article:
"The week of conference tournaments would serve as the first week of the NCAA Tournament, with the field trimmed to 64 or 68 teams in the following week."
Does this mean that the conference championships would be eliminated in favor of this plan? Another article mentions at-large bids - so doe not seem like proposal is strictly a play in. Will be interested in seeing more details.
