Sweep Georgetown and finish the rest of the games at 5-4 gives us a 12-9 record. (That means going 8-4 over last 12)
Georgetown would then need to go 5-1 to finish above us.
Win 2 from Georgetown and still finish the rest at 5-4 gives us a 11-10 record. ( That means going 7-5 over the last 12)
Georgetown would then need to go 3-3 to finish above us.
Since 4th place is now at one game over .500, it's possible for 4th place to finish either 1 or 3 games over .500.
I believe we can do this but we need to win at least 2 if not all 3 from Georgetown or it would be nearly impossible to make the 4 team tourney.
