I made the mistake of crowning Guidry before I realized he was joke, so I don't want to crown Heatherman just yet.
However, if one cannot see that Heatherman has absolutely made a difference, then you are not being objective.
Sure, you can say that Heatherman has better talent/players than Guidry did. While that may be true, Guidry also had NFL players (Kiko, Tyler Barron, Mishael Powell, a few others) and Guidry also had the current players (Bain, Mesidor, Bissanthe, Moten, others) that will be in the NFL. Guidry couldn't do anything with them. He actually hindered their development. We see the difference Heatherman has made for Bain, Mesidor, Moten, Justin Scott, Popo, Damari Brown).
If Heatherman was our DC last year, we would have made the playoffs. I don't think we would have went very far due to our secondary, but we are in the playoffs. Would have also had an answer for GT' qb who couldn't even throw a pass that game.
