Purdue was 5-3 in the Big Ten in 2012-2013 beating Wisconsin, Michigan St., Northwestern, Michigan, and Indiana. Losing to Penn State, Iowa, Illinois. That was their best finish in years and could be considered competitive for that single season. However, Purdue will never succeed in wrestling, if consistently being competitive in the conference is the metric, as Purdue is not willing to financially support wrestling to the extent of other schools.
It doesn't matter who the coach is because if the coach is good, he will find more money somewhere else. So, if you want to change wrestling at Purdue you had better start with the financial structure of the athletic department. Anything else is a complete and total waste of your time. Someone prove me wrong.
