But people saying NFL teams should impose limits on work hours are fooling themselves. You can change a policy, and you can even change the locks, but you can't change coaches unless they want to change themselves. Kubiak will be back on the sideline on Sunday, and Fox hopes to be back by the end of the season. Good for them. They love what they do. I hope they have long careers, and long lives, and that they don't confuse the two.
