Football on many levels is a simplistic game. Get a bunch of big brutes and slobberknocker an opponent into submission.
But officiating, well, that's another matter. It's not as easy as it looks. So if you think of yourself as Mr. Know-It-All, here's your chance. USA Football has posted an online test that college referees take to check their knowledge of the rules.
You'll have to sign in and identify yourself as "non-staff official." (Thanks to the Orlando Sentinel's On Campus for this.) The test is 100 questions, with the first 15 true/false and the remaining 85 multiple choice.
