After you are finished reading this article, you may think that I'm trying to make excuses for the Saints' 29-24 loss to the Redskins in D.C. This, however, couldn't be further from the truth. I believe that the Saints shot themselves in the foot by not scoring late in the fourth quarter and not being able to keep the Redskins from scoring.
Having that said, just imagine what it was like out on that hot field (90+ degrees) in the afternoon wearing black jerseys. The only thing that could've been worse would've been to wear the black pants along with them.
It is said that black clothing absorbs more light than white clothing, causing the wearer to be hotter, therefore causing the wearer to tire easily. The Saints looked tired, maybe this could've been the reason. The Redskins didn't look tired, but they were wearing white, as you can see in the photo above.
The Saints' colors were established to represent oil. With New Orleans and Louisiana in general having such a huge stake in the American oil market, and the first owner of the Saints being an oilman, black and gold seemed to be the logical choice for the colors, as oil is commonly referred to as "black gold."
Maybe the Saints should consider doing away with the black as a jersey color and choosing a new jersey color, maybe even gold, which would still be hot but not as hot as black would be.
With the Saints playing half of their games in the air-conditioned Louisiana Superdome, this may not seem like such an issue, but when you're a game short of the playoffs and you lost that game in very hot conditions wearing black jerseys, then it can become a very big issue.
As far as I know, there isn't another NFL team who wears black jerseys except for the Jacksonville Jaguars and the Detroit Lions on occasion. If you know of another that does, feel free to correct me. I'm not saying that the jerseys were the problem, but they certainly couldn't have helped.
