Rapoport obtained a statement from Wilson on Saturday shortly after reporting the position coach's departure.
It's interesting that Wilson, who had one year left on his contract in Pittsburgh, would make a seemingly lateral career move away from friend, Mike Tomlin.
"I have been on staffs with Mike for close to 10 NFL seasons and there isn't a better coach in the business," Wilson added in the statement. "I just got to a point in the progression of my career where I felt a change of scenery might be best for all parties. The Steelers allowed me to explore other opportunities. They are a great organization and once again showed why they are the class of the NFL."
It is possible Wilson believes a change will help him move up the coaching ladder in the future. Working with all-world running back Adrian Peterson must have been an intriguing prospect for Wilson as well.
