Unverified. To achieve achievements do the following:
Select every single team in Franchise mode and just simply sim everything. Throughout the entire season anyone who breaks "GAME" and "SEASON" record achievements will count for you they get unlocked.
Also, if you sim seasons your overall madden level will go up anywhere to 2 - 3 levels a season. Once the Superbowl and Pro Bowl are done just exit and go to "Play Now" Select no for save and then restart. You can easily get to Madden level 40 in about two hours and unlock almost every achievement. This also works for your SuperStar character.
Hint - Free Training Points (Defensive Players)
You can automatically get max 7 training points before each game in franchise mode, on an Xbox 360. It seems to only work for defensive players and I'm not sure why.
Pick 3 defensive players to train and choose Bench Press ALL-MADDEN for all 3 regardless of position and ability. As soon as you see the first guy on the bench, push START and choose QUIT. The game will ask you are you sure, you'll lose progress so say YES.
When the game exits to the next screen, all 3 guys will have 7 free points to add. It may be patched down the road, so use it or lose it!
HInt - NCAA Player Importing Failure
Playing NCAA 07 and doing Campus legend and then importing your player into Superstar doesn't really help you.
I had a Campus Legend (RB) and won the Heisman 4 times and it still doesn't determine whether ot not you get drafted by a good time and drafted. I was a starting running back for the Michigan State Spartans and ran for over 4000 yards my Freshman year!
I entered Madden 07 and kind of cheated until I got to the Denver Broncos. I ended up getting drafted 4th Round pick 11. The previous picks I was picked by the Miami Dolphins, Dallas Cowbays and the Tampa Bay Buccaneers.
I ended up with an 88 overall and had a speed of 97, agility of 99, awarness of 99, and everything else was like above 90.
We ran alot of trick plays in which I would have to Throw the ball down field for the TD. The best playre in the NCAA and the NFL and I get drafted 4th Round Pick number 11. I should've been picked in the 1st round.
