Ferentz's name came up every year for potential job openings throughout most of the 2000s. His agent was ruthless, using that to get multiple contract extensions and pay raises and other things like assistant raises. At one point Ferentz was the third highest paid coach in the entire country. His extension as recently as 2016 made him the 8th highest paid coach. It also validated him. "Turning down" NFL offers and staying at Iowa helped build his reputation.
Wisconsin has literally had two coaches take other jobs in the past eight years! Bielema and Anderson both left on their own accord. In fact, Wisconsin is on its fourth coach in the past 16 years. The three previous ones all left on their own, either retiring or taking other jobs.
I am probably in the minority, but I think it is a good thing to have PJ's name come up a lot. It says he is well regarded and we should be trumpeting that we have a coach in demand. It reinforces the idea that we have a big time guy. And every time he stays after his name comes up, it only validates that he wants to coach here. It just continues to build the brand.
