Ideally, the delivery truck pulls into campus a couple weeks before the truck's contents will be used.
Sometimes though the truck arrives just in the nick of time, the day before the game.
The delivery guys begin unloading stacks of cardboard boxes, each containing alternate uniforms to be worn by that Southeastern Conference school's football team. A hundred to 150 sets of helmets, jerseys, pants, socks, cleats and more. For one specific game.
Tradition is a big part of college football's appeal. That's certainly the case in the SEC, where many teams' uniforms today look much like they did 30 years ago or even back further.
