I have been watching it for over 30 years, think it is great. No favourite team now, used to like the Oakland Raiders, but they have relocated twice and are now the Las Vegas Raiders. Too much like Franchise FC, really.
The Browns are completely fake, they are only doing well because of an easy schedule, like as if we played C*v or F*r*st every week. San Francisco have imploded, difficult to see beyond Mahomes and the Chiefs for Super Bowl LV .
The structure of NFL is attractive too, as the draft system and salary cap give all the teams a chance to be successful, they want games to be close to maintain high TV viewing figures. Good stuff.
