It would be very difficult as their head to head record versus BU is 0-1, BC is 0-1, and St. Cloud is 0-2. They are already losing the comparison with BU and they currently have the higher RPI. They will not be able to flip this comparison. They also will not be able to flip the comparison with BC because of lack of common opponents left to play (BC has some possibilities, but even losing out these common opponents wouldn't flip that comparison. Denver could possibly get past St. Cloud and UND by flipping the RPI comparison and not losing if they were to meet head to head one more time (I am assuming if they met head to head one more time there would not be an opportunity to pass either team as that head to head matchup would be at the Frozen Faceoff, leaving too little time to come up with the RPI points. They could also pass Providence and Quinnipiac if they flip the RPI.
Bottom line is Denver would have to pass numerous teams in the RPI category to jump into a top seed and their PWR loss to BU could force them into tie breaker scenarios.
