Utah went out and got Huard over the offseason, a very highly-regarded JuCo transfer QB who is a senior on this team. They also felt good enough about the position to let their pig farmer, Bryson Barnes, go...
Even if Huard was better, it's very possible that Ludwig had Wilson pushed on him—that because of age and family connections, KW felt like it would be better to give FR Wilson experience instead of running with Huard.
Regardless, I don't see this as justifying an in-season firing.
