That's actually one of the reasons I love Madden. Literally Madden remade me into a football fan. I'd gotten so tired of the coverage being only about the QB, one RB, two WRs and maybe a CB I'd actually stopped watching the game for a few years until a friend pointed me to CBS and Madden. But even Madden doesn't really dig deep into it very often, he can't the audience will lose patience. The standard football audience doesn't really want to hear more about the blocking scheme beyond "they did a good job picking up the blitz and giving their QB time to make the play", maybe a quick "BOOM look how he knocked that pass rusher down", but they're not gonna sit for hearing during every possession about how this block worked because of how the lineman got square to the rusher and picked the correct plant foot. Your average football fan would be bored to tears by that kind of coverage, which is OK but it shows why your average football fan is not also your average hockey fan, hockey fans eat up that kind of coverage, we want to hear about how the shooter dragged his toe to keep his stick extended and improve his angle on the net. Neither is better than the other, they both simply are.
This isn't football school. If you are fan of the game of football you probably have an understanding of blocking schemes and how recievers run their routes. Football is an exciting sport with drama,skill, strategery, and every NFL game means something to the team. NFL football is an event, not one of 82 games or 180 or whatever baseball plays.
If a person grew up playing football they know the jobs of each position, now the anouncer needs to anounce whats happening, not show us how informed he is about the game. As a fans knowledge of the game grows you start noticing and appreciating the DE and the Tackle having that brutal battle or the 80 yard drive all on the ground.
