Here's what I said not immediately at the time, but the week afterward.
"There was a realistic window that we were going to hire in, and I think we hit the very top of that window (if not just above it). We were either going to bring in a G5 HC or a P5 coordinator... and we got a great, successful, national championship coordinator with several years of coordinator experience in the Big Ten. Given the size of the ballpark we were playing in (we weren't about to drop $4.5M on a proven coach), that's a home run.
That doesn't mean, though, that Ash is going to be 100% perfect and right about everything all the time, and that any questioning of his moves is forbidden and means you are trying to tear down the program. He's a new HC with great resume/pedigree, and he's got big plans - but not all of them will work, and he'll learn as he goes.
This isn't an all-or-nothing thing. You can be very happy with Ash, but question the Mehringer hire. You can be very happy with Ash and Mehringer, but wonder what's going on with recruiting right now. You can love Ash, but not be sold on Hobbs yet (or vice versa). There's lots of "new" right now, and it's all speculation/conjecture until we start seeing something on the field - and while this is a bit of a honeymoon period and time to be optimistic, people have gotten their hopes up before and been frustrated, too."
That last paragraph was pretty much where I was at that point - happy with Ash (best I felt we were going to get, given our circumstances), but questioning the Mehringer hire. Still trying to remain optimistic, though, that it would all work out.
Then Niemann was hired a couple of weeks later, and the optimism started fade. I could rationalize Mehringer a bit, but was having a much harder time with Niemann. That's probably when I started to doubt Ash... just about three weeks after he was hired. Was still waiting to see the product on the field, though - and the early recruiting returns were good over the summer.
Then the season came... and by October I felt he blew the very small window he had and likely would never be successful here.
