The 2 brothers that operate Football Scoop are childhood/high school friends of Peyton and Eli Manning who still have close contact with them. The older brother branched off and he has the site Coaching Search. Might wanna pay attention to what they have to say. They are very well connected in the industry.
Yeah, I know the dudes that run it. While it isn't exactly slick and there may be a bunch of typos, they have legit knowledge and are very connected to the coaching world.
