Having to make sure you get good stats with your franchise player and doing certain things like sacks and TD celebrations. I knocked out over half of them for about 650 GS in a few days. I was trying a lot of things as I played games for achievements so I probably could have cut it down to maybe 2 days for 500-600. You will need 2 playthroughs on campaign mode to get 1 or 2 achievements, though."
