So the possible margins of victory in an NFL game that goes to overtime are:
2, 3, 5, 6, & 9 pts.
3 point wins being the most likely, followed by 6, then 2, then 9 and 5.
In the CFL its possible in overtime for a team to win by 12 or 14 points, I've seen it.
I've never seen an NFL game where a team won by 5 or 9 pts.
Discuss.
