Don't tell anyone, but the so-called "secret scrimmages" are upon us. You know, closed-door scrimmages -- mostly between Division I teams -- in which the NCAA doesn't allow publicity or even stats. (For a complete explanation of what these scrimmages are all about, check out this article from ESPN's Seth Greenberg last October.)

They started last weekend with Colorado playing at Boise State, and there are about 15 matchups this weekend -- including the annual North Carolina-Vanderbilt scrimmage in Memphis on Saturday.

Remember, keep this hush-hush -- these are secret scrimmages, after all.
