You can quantify without diminishment. Here's an example I think fits.
No one that I know of diminishes the run Oklahoma had under Bud Wilkinson from 1953 to 1957. Undefeated, for that long? Impressive.
If we quantify that OU run?
-- In '57 they didn't play a team that finished with more than six wins until they lost to Notre Dame.
-- In '56 they beat a 8-2-1 Colorado in route to a 10-0 season. None of the other nine teams had more than four wins on the season.
The stretch reads like that, literally. In '55 they won their bowl game against a 10 win Maryland team. Good win! It was part of a season where their other "competition" was a 7-4 Pitt team.
In that stretch of seasons OU was 50-2-1. Out of those 50 wins seven had six or more wins in those seasons.
OU, and Clemson, built resumes on the backs of runner-ups to the also rans.
