I will always be grateful to Mr. Benson, Mr. Loomis, and Coach Payton for the opportunity they gave me to play the sport I love in front of football's greatest fans, amongst some of my best friends.
"We accomplished great things during my time with the Saints, including winning the first Super Bowl in franchise history, and I am proud of my contributions during the decade I wore black and gold. My wife Racquel and I will continue our commitment to improving lives for New Orleans' youth no matter where my next stop in professional football takes me. I'm in good spirits, thankful and focused on training. My family and I welcome the next chapter in our NFL life. Who Dat!"
