What I think this "argument" is saying is---Where do you get all of your football knowledge? And the couch on Saturday's and Sunday's does not count.  Until you have been on the field, under the same circumstances that these coaches have, we might need to bite our tongues and cut them some slack.  I have been a player on the field and my coach has taught me what I needed to do, but if i didnt perform it, it wasn't his fault---it was mine. And I am man enough to admit that.
