As a Brit born in the mid 70's I didn't discover NFL until the mid 80's. I sat with my mom and watched a Denver Broncos game featuring John Elway. Later on I caught a San Fran and they quickly became my team.
Tried to follow it sporadically until I emigrated to Canada a few years ago. Now I can watch all the football I want.
I played the Madden games to death but when it came to management games I could only find Football (soccer) management games, which I tried, but they never scratched the itch.
I just discovered DDS Pro Football and am trying the Demo though I must admit, none of the rosters are filled so I am at a loss. Trying to figure it out.
Wish me luck.
