I think it would be impossible to follow Snyder if he retired after 2012 or 2014. I really don't see it as much of an issue now.
I agree, unlike previous years, or when Snyder retired last time, many people are calling for a change and some negative and frankly ugly press has surfaced as a result. It will never be easy to follow Snyder, but if Taylor gets a good name that engages KSU fans I doubt it will be an issue early on. After a few years winning will be the judge.
As for Prince, it is still baffling that Wefald, who did a lot of good for KSU, thought that an average offensive coordinator with three years of coordinating experience could replace Snyder or enjoy fan support. Heck, Virginia wasn’t even good when Prince coached there (21-19 in ACC play during Prince years and 12-12 when Prince was an offensive coordinator).
I think Taylor will be much smarter and get someone with proven head coach or coordinator experience. Early on people packed the stadium for Prince and they will do it again for a new coach... they just need to relate early and win and fans will follow.
