Expand the Tourney Field?

There is too much talk about expanding the field from 65 to a higher number, which is ridiculous. The reason some teams don't make it is there are too many weak teams getting automatic bids by winning their conference tourney. If there is a problem with too many deserving teams being left out, I have a solution. If a conference tourney champion is not ranked in the top 65 based on the RPI, they would not get an automatic bid, but could be considered for an at-large bid. This process would eliminate the pretenders, and produce a bracket that is completely solid in every round, including the first round.
