Here, glance at this first:
Not many new details, but just an acknowledgement that change is being discussed. Two points of legitimate concern are in the details, though.
1) Should ESPN (or any other prominent media member/partner) have their metric included in this? Conflict of interest is extraordinary high, even if the formula is known and independent.
2) Some of the metrics are predictive of future results, while others attempt to quantify only results that have already happened. You just can't blend the two together. In order to have a useful composite, the data you're including needs to be of the same format (using the same data) and needs to have a common goal.
The NCAA has said in the past they review resumes and try to prevent projecting out what happens in a bracket. Some of these metrics are designed with the specific goal of projection. If the NCAA wants to use these, fine, but it must acknowledge the change in the selection process publicly.
Two things to think about as discussion continues.
