Marciano is a problem & needs to go.
I wonder if Kubiak needs to, ironically, say something to McNair about Marciano???
Personally, I don't believe that firing a person is or should be the only recourse when someone isn't performing to standards. As a head coach my job is to make sure my coordinators are getting the most out of their position coaches who in turn should be getting the most out of their players.
I would think Marciano would be more like a coordinator as he most likely reports directly to the head coach. Like the Tandon doss return. When Kubiak was asked about the breakdown in coverage he replied there was no breakdown in coverage. We had 4 unblocked players there to make the play. They didn't, Tandon Doss did & you know the rest.
Still Marciano's fault, not saying any different, but the problem (in that instance) is different from the perceived problem. Last year, in addition to poor play, there was also a lot of penalties so even if we did cover a kick well, or get a decent return, the penalty negated it. This year I'm seeing a lot less penalties. Different penalties if nothing else.
Having said that, I also think the Texans are slow to remove a person that needs to be removed. This isn't a new problem. Last year wasn't the first year this was a problem.
Just like our defense, Kubiak had his guy & he did not deliver the product we needed. Instead of firing him, he brought in Frank Bush. Performance didn't improve he ended up firing Smith anyway. If he thought replacing Smith was the best thing for the team, he should have done it when he brought Bush in. All he did was prolonged the inevitable.
Joe's assistant is probably Joe's replacement. He probably should have been brought in last year, they're probably prolonging the inevitable.
