Nick Saban is Overrated?

So, I'm minding my own business, scrolling through social media when I get a notification saying there's a discussion about whether or not Coach Nick Saban is overrated.  Of course, being from Alabama-- and Tuscaloosa no less --this caught my eye!

Now, I don't have to be a Tide fan or a fan of any other team to know that those words are borderline blasphemy in my town.  So, I decided to give the video a watch.  You should, too.

Is this a valid argument?  What are your thoughts?
