I know you think that's a gotcha question, but I want to swing for the fences, which means I'm cool with taking a chance on someone who hasn't had HCing experience yet vs. the 61-year-old with playoff success 10-15 years ago while only having regular season success with loaded teams.
We don't have Brett Favre, Aaron Rodgers, or even Dak Prescott here. We aren't going to have a roster full of talent. I don't think McCarthy has ever shown an ability to be competitive with sub-par talent.
Who do I want? I'd rather Brady or Glenn between the three. If they fail, at least we tried to hit a homerun.
