Oh I agree, I think he's way above average in the getting players motivated. But his in game management stinks. Another example....in Chicago, down 14-0 in the 1st quarter. 4th down in the red zone. Easy call, take the points. Nope, he went for 4th and goal and didn't make it. We ended up tying the game and going to OT. Those 3 points <may> have helped us win.
And he already had HC experience when we hired him. 12 games or so in Miami.
In the NFL, wins often come down to a play here or there. Making coaching mistakes every game will put you at a disadvantage that may not be easy to overcome with such a horrible roster.
With that being said, I would love to see him with a talented roster. He may be able to motivate the team so well that we win by multiple scores. His mistakes wouldn't be as glaring.
