OK EZ,
I just want to be clear on the rules.
If the team you pick to win loses, you're out.
Of those that pick the correct winning team, the closest to the total points scored (both teams combined) wins.
I'm not trying to be dense, it's just that I've been in these before where the differential is calculated for each team separately and then added together.
For example: Let's assume one person picks the Pats to win 20-17 (37 total points) and somebody else picks the Pats to win 24-14 (38 total points), and the Pats end up winning 21-14 (35 total points)
If it's based on total points the first guy wins.
If it's based on the combined differential for each team calculated separately, the second guy wins. 3 point combined differential vs. 4 point combined differential.
Either way is fine, you just need to make sure everyone understands the scoring, otherwise you run the risk of having a bunch of whining welshers on your hands.
