Everyone knows ... the Saints are basically UNSTOPPABLE on the road when they chow down on Popeyes before they hit the field ... and they tweeted pics showing them inhaling the chicken before their big playoff victory against the Eagles last week.
Now, the President of Popeyes Chicken tells TMZ Sports ... the company is putting the entire weight of the Louisiana-based organization behind the Saints and have provided them with 375 pieces of chicken to hold the guys over during the flight from N.O. to Seattle.
"As a direct result [of Popeyes chicken], they won their first playoff road game," the President tells us ... adding, "They have a 100% win rate in the playoffs when they eat Popeyes."
We're told the guys will be getting 125 three-piece meals (90 spicy meals, 35 mild) which include mashed potatoes and cajun gravy, red beans and rice, and biscuits.
When we asked the President about critics questioning eating buckets of fried chicken before a football game, Mr. Prez told us, "It's definitely not what you'd think, but it's what they want. And you can't argue with success."
The flight is scheduled to take off in just a few hours -- good luck to the people on lavatory duty.
