Well if you never heard of "this guy" that must mean he has no business giving any type of analysis like the people you have heard of .
What I can't fathom is how ANYONE doesn't know the sun's supposed "path". As actually pointed out on the Hard Knocks program the sun doesn't rise or set. It stays where it is and its the earth that's moving.
BTW: the guy you never heard of actually comes from an enormous football family all of whom starred at USC. He does provide insight into individual guys he played with in terms of personalities as well as coaches, etc. Some of the comments pertain to stuff that you never hear about such as Peter...would eat spiders before a game or Sammy...was a certifiable...He's also extremely self deprecating which I find unusual in the field of sport blabber mouths. But he can get a little juvenile and that turns me off. But his insight into such things as play calling nomenclature is something I had not thought of and never heard anything on it either here or even on talk programs like the one that you mentioned. So I found it interesting.
