There are still some bid stealers, but it does seem like less this year.
Obviously any of the major conferences (Big 12, Big 10, ACC, Big East, SEC)...if obvious at large teams don't win it, that's a bid stealer. But there are enough good, top end teams in each of those conferences, that its unlikely to get down to the 5,6,7th + place teams winning it. Which is what it would take. SEC it'd take 11th or 12th +, maybe Big 10 too... not gonna happen. Maybe ACC or Big East??...
Other conferences to keep an eye on though...
American Athletic... If Memphis doesn't win that tournament, that's a bid stealer.
West Coast... If Gonzaga or St Marys don't win that tournament, that's a bid stealer.
A10...If VCU doesn't win it, that is a bid stealer.
Mountain West... there are 3-4 teams currently in at large consideration, if one of those doesn't win it, that's a bid stealer.
There haven't been any other bid stealers win it thus far, and none of the other conferences have any at large candidates.
