I did play Static Pro Football, but I don't remember it as well. I think there are similarities. There are rules online for paydirt. Just google paydirt and you can find different sites for it.
The bottom line is that each team has a chart w/ offense and defense and special teams. There are 4 run plays and 5 pass plays to choose from. The defense can pick 1 of 6 formations. All have strengths and weakness. Each player rolls on the chart and there are rules for how to prioritize the results, whether it be defense chart result, offense chart result or combination. It also has rules for razzle dazzle plays, field goals, punts, onside kicks, etc. It's easy to pick up and start playing. The only thing you don't get are instant replay reviews
