You're right, they did both play St. Lawrence. RPI beat St. Lawrence by 48-0, while SJF scored a 28-23 win, so that one also could be counted as a comparative score in favor of RPI.W21- Very difficult to find any sort of odds on this one. Seems these last minute ECAC bowls were not on many radar units. The only one I can find is that we are a 9.5 point favorite. You are absolutely correct about common opponents and the results but I had thought both teams had played St. Lawrence also. This has been a surprisingly good season for us and we were within range of turning around one of our losses (Ithaca) which might have changed the ending of this season even if it only moved this ECAC Bowl game to our home field.
Then, again, I can recall back in 1966, someone calculated that by comparative scores, RPI would have beaten Notre Dame that year.
