Perhaps, although I'm not sure how you can say that Minnesota, Green Bay, and Chicago all have coaches who "have brought their teams to the top of their respective division," considering that:
(a) they are all in the same division,
(b) only Minnesota is really at the top of the division, with Green Bay hovering around mediocrity and Chicago in a free-fall,
(c ) Minnesota's coach was widely considered to be on the hot seat this season and lucked out by getting a youthful Brett Favre, and
(d) Chicago's coach is almost certainly going to be fired at the end of the season.
I don't necessarily disagree with your approach or argument, just pointing out it isn't as clear and obvious as you would like it to be.
