The average number of points scored by each team in a college football game is likely somewhere around 28. But if you want to know a "common" score, each team generally scores in multiples of 7 and/or 3. So "common" scores would be 3, 6, 7, 10, 13, 14, 17, 20, 21, 24, 27, 28... etc. Although once a team scores a safety or a 2-point conversion, the "common" numbers will be different for the remainder of the contest.
