Really?
Demarcus Ware (on Jason Garrett): “I think he's a great coach. What a lot of people don't understand is he's a motivator. He'd give speeches before meetings and that's what coaches should do. He was a good delegator but he could go into any meeting room and know everything: what people are doing, what's going wrong and how to fix it. That's how you know he's a good coach.”
Let's look at the part in bold, shall we? He's good at knowing everything? Romo said he wasn't an X's and O's kind of coach. And if he knows how to fix everything, why do the players and especially the coaches keep making the same mistakes over and over in games? That doesn't sound liking fixing anything to me.
Garrett could be a very good motivator to an extent. He could be hampered by Jerry's culture....but he's a terrible head coach (at least in the atmosphere that Jerry presents). There is no argument to be had about that. The results speak for themselves. It's time for change.
