How do you..

Scout your upcoming opponent or is it possible? I'm playing single player mode.

You can get a quick scouting report of your next opponent by clicking on the "View Scouting Report" link in the Simulation Window.

For in depth scouting, review the team's game logs for the prior games and take note of the formations, length of passes, directions of runs, blitz frequency, etc.

But it's Single Player, so I wouldn't waste my time ;)
