"[I'm] excited," he told the Saints' official website. "It's a great opportunity. I'm very very blessed and thankful for the opportunity to be a part of the Who Dat Nation. Very much looking forward to it.
"To be a part of such a great franchise and coach Ryan and coach Payton and the guys have really showed me a lot of love and respect. They supported me and we kind of connected on a couple of ideas and it was pretty much a perfect fit."
