The Bucs on Sunday visit Houston's Reliant Stadium, which, as you might know, has a retractable roof.

It remains to be seen whether the Texans will open up the roof for the game, and they'll probably not make that determination until Sunday morning. They adhere to an interesting little formula called the "50-80 Rule" to decide whether to open the roof.

If goes as follows: if the game time temperature is between 50 and 80 degrees, the roof is supposed to be opened. Sunday's forecast calls for a high of 80 degrees but includes a 30 percent chance of storms. If rain is anticipated, they'll obviously keep the roof closed.

Probably won't have much impact on the game either way, but consider this your factoid of the day.
