It's too early for me to say yes or no definitively. But last year I said it was time for some kind of change to the offensive side of the ball, specifically, something related to how they recruit and coach QBs.
If the results of this season effectively mirror the prior two seasons, then something needs to change to get better results, right? If the results improve, then maybe the plan the staff was working is on an upward trend. I think we'll all agree that the expectation should be to be playing in the MACC in Detroit.
They did just change the QB Coach a couple years ago. Isphoding's first recruit was Quinton Maxwell (2015 class), and he has a couple recruits who have given a verbal for 2017 that look very good, but there was no QB in the 2016 class since he chose to only offer QBs that he really wanted, rather than continuing to make offers until he finally got someone. I personally didn't have a problem with that approach, but I know some were uncomfortable with it.
With Maxwell having yet to play, it's definitely too early to see how well his recruits will turn out. It's also difficult for me to comment on how QB improvement under Isphording, since Vick and Sprauge had so many problems with injuries that I don't think either had a fair chance to show their true potential.
