Willis - please see the previous post (about the rules and format for this year's Pick'em) about how the tie-breaker works.
@toddpedlar can chime in to provide the mathematical/formulaic nitty gritty.
But long story short it factors in the differential between the guessed winner's score and the actual winner's score AND the guessed loser's score and the actual loser's score noting the difference between those.
In this case Jason guessed the score would be 37-17 and 3dawg guessed the score would be 31-27. The actual score was 23-13. In the case of Jason, in terms of raw numbers, his guessed winner score was 14 over actual and his guessed loser score was 4 over... In the case of 3dawg's raw numbers, his guessed winner score was 8 over actual and his guessed loser's score was 14 over.
This produced a score differential of 16.12452 in the case of 3dawg, and 14.56022 in the case of Jason. Lower is better.
