BTW, if you do, please don't do a point spread approach. My reasoning is that say the score ends up 35-31 and one person predicts 10-6, while another predicts 36-31, it would seem to me that 36-31 is a lot closer to the teams' actual on-field performance than 10-6 even though the lower score nailed the point spread.
A more rational way would be to take the difference between the individual scores and combine the total difference. In the case above the total difference for 36-31 would be "1" while the difference for the other score would be 51. Also I don't feel that a person with the wrong winner should win unless everyone predicts the outcome incorrectly.
