Hey pastime Steve,
The game are you thinking about is called XOR Nfl Challenge
XOR NFL Challenge - YouTube
The circles would move along the base paths, defensive players' "uniforms" would move to the location of the ball based on the new physics engine, etc. I'm dating myself, but I'm thinking back to an NFL computer PC game where the X's and O's would move up and down the playing field, except with OOTP, the uniform circles would be reflected in the action.
