That's a college football conference, but here we're talking about the number of big football games over the long weekend. And the number 10 is artificially conservative.
In college football, the high-intensity match-ups include Arkansas versus Louisiana State, Ohio State vs. Michigan, Notre Dame vs. USC, Alabama vs. Auburn, Georgia vs. Georgia Tech, Clemson vs. South Carolina. Add a contest within the Big Ten itself (Penn State vs. Wisconsin) and that's seven big games right there.
The National Football League will contribute many more. Here are just the three to be played on Thanksgiving Day itself: Houston Texans vs. Detroit Lions, the Washington Redskins vs. Dallas Cowboys, and (in the evening) New York Jets vs. New England Patriots.
The list could go on of course. (Fill in the blank with your favorite local teams.)
