Saints planned to interview Mike McCarthy; McCarthy didn’t garner enough interest from Saints and will take a year off

Not really. No. He inherited a good team in Dallas and still underachieved. The guy was been fired twice, and one of those times was a player mutiny. Good coaches get extensions, not fired. Especially in Green Bay.
He was there for 13 years, it wasn’t on one contract. Using that logic, no one should have hired Reid after he was fired by the Eagles.
