Even then people didn't like him. All the credit was given to Kubiak for the hot start.
The hatred for Carr ridiculously started with the Chipotle thing. But it continued with him incorrectly yelling at Olave and then getting into an argument on the field with McCoy. Then he wasn't here for the Super Bowl or Mardi Gras while Jameis Winston was here showing people how great it is to be here. So rightly or wrongly, he lost the fans early and has done little to change that. And at this point, I doubt anything could change it.
Winning will turn down the heat, but he will never be liked or certainly not loved here.
