The main reason this became the highest scoring offense under Bret was because of John Paddock. Losing Lunney would not be a bad thing in my opinion. Not claiming to be an expert, just don't feel he is or ever will be what we really want. It would be great if he proves me wrong.Chryst hasn't been an OC for 11 years and was fired from Wisconsin primarily because of their lack of offense. He looked great with Russ and it's gotten progressively worse since. Moorhead would be even worse - Oregon has finished in the top 30 offenses every single year in the past 19 seasons except the two seasons when Moorhead was their OC.
Scheelhaase would be an intriguing hire but I think that would be a tough sell. Iowa State had an excellent season, especially when factoring in the pre-season suspensions. Their offense was substantially improved from last year. He likely gets a new contract this offseason from the Cyclones.
I really like Lunney and believe in the strides taken the past two seasons. This year was the highest scoring offense for Illinois under Bielema, best passing offense since Scheelhaase's senior year. Next year's schedule looks fairly soft (for the new era of P5 conferences) and the offense could take a serious step forward with Altmyer. If I'm Lunney, I stick it out one more year and press my luck that bigger programs could recruit him as OC or he could get some head coaching looks.
