This is something we come across often and is a pretty strong betting
angle for NCAA Football, usually around the mid point of the season.
You'll find points in the season where one team has played
3 games more than their opponent, playing more is often a physical
disadvantage for a team.
Pay
attention to situations like this, particularly between divisional opponents, also check
if the 2 teams prior history favours the team with the fewer games played.
