I think the Penn 93-94 and 94-95 teams would have been on the bubble.
93-94 team only 2 regular season losses, both on the road, one at McGonigle Hall to a powerful Temple team ranked 12th in the final AP poll. This in a year where Penn itself was ranked 24th in the last regular season AP poll of the season.
Major problem would be Penn simply not playing any good teams that year, although they certainly won their share of away games against major conference squads.
