In 2003. After Del Rio left, Fox wanted Mora first. In his interview, Mora supposedly acted like a cocky, arrogant twit (shocking, I know).
WHat was the first time Mora snubbed fox?
Also, i was under the impression Trgovac didn't like Fox and that fox had his fingers too much in his defense and that's why he didn't come back/fired (they say he was the one that decided not to come back).
As to Trgovac and Fox, right now it's all just speculation. If given the opportunity, he may turn it down too (assuming they don't hire the Saints guy they interviewed).
There are also rumors Trgovac could be a candidate for the eagles DC job.
