Goodell is already investigating leads that Saints personnel were involved in some way (sabotage) as payback for penalties from "BountyGate".
NFL officials are checking alibis for the whereabouts of all Saints players/coaches at the time of the outage. Early indications are they are homing in on Sean Payton. Evidently he has a background as an electrician.
Google "Sean Payton Electrician" and you'll see what I mean. Stay tuned while the power is on.
