If BC jumps Cornell, we'll STILL be 8th and out. We'll have 29 comparisons won and BU/Cornell will both have 30.
If Ohio State jumps BU, we're STILL 8th and out. We'll have 28, and BU/OSU will both have 29.
It would take BU getting passed by both teams below them for us to move up into 7th. It would surprise me if BU lost two of their last four regular season games, so BC really has to hope to get that BC/BU semifinals matchup.
