And it wasn't good.
"I don't think it's a great fit, and I don't think it's great timing, and here's why," said Leinart, a free agent quarterback who was cut by the Cardinals during Whisenhunt's tenure. "You look at his tenure in Arizona -- only two years, he had success, and in those two years, [quarterback] Kurt Warner ran that football team -- I was a part of it.
"Every single Monday, Kurt Warner would come in and implement 20-to-30 new plays which he would say, 'I want these in my game plan.' We became a spread offense and we became Kurt Warner's offense. Then Kurt Warner retires, they go 5-11 twice and they go 8-8."
