Not only is that true, but it's also true the Saints can't make a formal organizational announcement until after the Super Bowl, unless the Eagles give them written permission to hire Moore, which they clearly aren't going to do.
Those rules do not apply to reporting by the media from unnamed sources. In the past, there have been reports in the nature of "X will be the coach, they just can't finalize or announce it until" and no team was penalized for those reports.
All we are getting from the press is "Moore is the (front runner, most likely, in driver's seat, really impressive) candidate." Not a single reporter is saying that "Moore will be the coach."
To emphasize, I am not saying Moore will not be the coach. I'm just saying that nothing that is known at this moment is enough to lead to any definitive conclusions.
