If BYU wins the WCC, they'd steal a bid. The others would be considered on the bubble if they lost in their conference finals. It's the same thing as every year on whether a 25-27 win team deserves a spot over a 20 win team in a major conference. ESPN has a good breakdown of bubble teams on their bubble watch. All of the above are on there under "work left to do". For comparison sake, Illinois didn't even make the list last week.
