Here's how I did it and you don't need to download a special roster:
1: Create your Franchise (can be online or offline) with any team.
2: Set difficulty to All-Madden and make sure the CPU does all the roster moves.
3: Turn off coach settings as well.
4: Now change role- Coach, new coach, pick the style you want, accept & continue.
5: Sim the preseason.
6: Go to league schedules and press cn_A to do force win. Select home if your team is playing at home (vs.) and away if your team is on the road (@). Do this for all your games.
NOTE: Away is on the left and Home is on the right
7: Do the same for each playoff game/Super Bowl).
8: Sim offseason letting the CPU do the work
9: Rinse and repeat steps 5-8 until you have all the achievements.
