FLORHAM PARK, N.J. -- New York Jets coach Robert Saleh likes to wear a black T-shirt that has "60%" emblazoned on the chest. No, it's not the percentage of cotton in the shirt. It's certainly not the team's winning percentage over the past decade. (If that were the case, the T-shirt would say 34%.)
No, the shirt is a nod to the Navy SEALs and their secret to mental toughness -- aka the 40% rule. Loosely translated: When you're so exhausted that your mind is telling you to quit, you've actually reached only 40% of your body's potential.
