There is SO MUCH material out there. So many on-line sources, and someone has to do the writing and commentary.
These are not well paying gigs. Sometimes the quantity of material generated is tied to the compensation.
And all that is fine but Who is doing the writing and commentary?
If it's someone who has two or three decades in football ... played a little in college ... coached a little ... maybe did some scouting. Doesn't have to be at the pro level. But such experience would probably require getting paid more. Heck, just someone who has followed the game for a long time would likely have a better take than someone who has a fraction of the years following the game.
It makes sense to see an article on Yahoo Sports and figure the author may know more football than the reader. But it may well not be true, especially when you look at the author's bio.
If the reader has a couple decades following the NFL and his team; and the article is written by a younger person, with no practical football experience (just a fan and aspiring writer) ... then there's a good chance the reader has much more knowledge about the game in general, and his team in particular.
