I am going to give you one example of why I like him. There are many reasons, but I am just going to give you one example.
Last year, Week 15, in Tennessee. The Titans were running over the Dolphins and had a 24-6 lead with less then 9 minutes left in the 3rd quarter. Just imagine to past coaches like Jimmy Johnson, Dave Wannstedt, Nick Saban and Cam Cameron. With that score, that late in the game, you were better off turning the TV off or leaving the stadium. The game was over at that point.
Sparano on the other hand, kept his players motivated and had them believing they could come back. The result? The came back and tied the game at 24 and forced overtime. Granted they ending up losing the game, but it was obvious that coaching is why they were able to come back and not just continue to get blown out.
That is just one of many reasons.
