That's exactly what most of us fans were asking at the time.  We just wanted to keep our same old plain jane "boring" power running game.  Sure, it's "outdated" and whatever, but it's what has worked for us since Alvarez came around.  Strong defense, SOLID offensive lineman, top of the country running backs, strong fullbacks, and just power it right down team's throats.
The "air-raid" experiment was a huge failure, and now we're a team without an identity, without our historically strong defense, and without the OL talent of years past. We still have pretty good running backs, but they can't do much of anything when the OL gets completely manhandled by other teams and is completely incapable of opening up any sort of a hole for them to run through.
It's really embarrassing to watch.  It's the first time in my lifetime that the Badgers have been "pathetic".  With the recent changes to the NCAA  (the "Big 20+", transfer portal, paying college athletes big bucks), I don't think that the Badgers will ever be competitive at football again (at least for the foreseeable future).  I think they would have been alright if they had stuck to what they've always done, but now with the failed identity change, few star athletes are going to want to play for a team that sucks and lacks the identity that they once had.
At least we still got women's hockey, women's volleyball, and hopefully the men's basketball team remains decent.
