I think a few people dramatically overreacting are making the community seem more divided than it is. You have a handful of blowhards who think this guy is absolutely terrible, and who are either trolls or not capable of getting over their own preconceived notions. However, beyond that it seems like most people see this as it is. We hired a pretty good defensive coordinator, who runs the style we prefer and has shown flashes of significant upside. Most of the rational debate is considering whether he can duplicate the instant success he has shown in his last 4 stops and then sustain it at some level beyond "pretty good".
This wasn't a sure thing hire by any means, but the real conversation is trying to see whether he projects from good to great and whether he can take the next step past that.
