I love McCarney, I'm glad we hired him.
But if you want to poop on Leach because he hasn't won conference championships... McCarney has won a grand total of 2 outright conference championships in 34 years as a head or assistant coach. One was as a DL coach at Florida in 2008, the other was in 1985 at Iowa as some sort of assistant.
If you don't want to count the one that Leach tied for in 2008, then McCarney only has 2 in 34 years, including zero as a head coach and I believe zero (not sure about Iowa) as a coordinator.
There's more to being a quality coach than outright conference championships. Hell, Dickey won four conference championships, and that doesn't do much to earn him any respect around here.
I like McCarney and he's a hell of a coach. But not by the criteria you keep using to mock and tear down Leach.
If Leach sucks because he didn't win outright championships during his 12 total years coaching at the D1 level... Then McCarney ain't that great, either. Because Leach probably could have picked up 1 or 2 if he'd had an additional 22 cracks at it.
Be consistent.
