That is what I do for league games. I don't know what the hell you guys are doing that spend hours doing it.

Scouting can take a very long time depending on the team...ironically, the power running teams are the easiest to scout and gameplan for, but it won't matter if your personnel doesn't hold up. The whole process takes about 15 minutes.
Scouting a good passing team can take me hours if I have the time and then a good 30 minutes to set up the AI.
I sometimes do the same for scrimmages, but not usually if they fall in the middle of the week...
