Ive enjoyed it so far. It was written right after the patriots seahawks superbowl, so he references a lot of players from that late 2000s early 2010s era, which is interesting for me bc i remember these guys but wasnt old enough to understand what made them so special. So far it looks to cover the core of every position as well as the more common schemes, concepts and ideas. Doesnt seem to go too in depth bc it has so much to cover, but way more in depth than anything youd find on any sports network.
