Madden NFL 15

This solution will net you all 10 Legacy Award Achievements!

This guide is a modified version originally made by WayzoftheRaven for Madden NFL 25 on Xbox One.

The solution works with any custom roster modified so that one team has every player rated 99. When I did the achievement I used a roster named SEAOP created by pensfan405 which modified the Seahawks roster.

Doing it this way should cut down the achievement to about 30 minutes.

1. At the Madden home screen, go to share. Download the pensfan405 Roster.
2. After the it is done downloading go back to the home screen, go to the right and go under Customization. Click Manage Files and then load the roster.
3. After loading the roster, go back to the home screen. Once at the home screen go to the Play option and select Connected Franchise.
4. Select Create Online.
5. Name the team anything you want.
6. Under Roster, choose custom.
7. Make your online league private and set a password (doesn't matter what it is)
8. The game will start importing your roster.
9. Once that finishes it will display "Begin a Career" on this option choose coach.
10. Select "Create a Coach"
11.The coach option you want to select is the "Team Builder"
12. In this instance since the modified team is the Seahawks you want to select them. If the roster loaded correctly you should see all 4 people rated at 99.
13. At the "Edit Coach Screen", just click "Accept & Continue"
14. At the setting screen the ones you want to change are the difficulty (set to "All Madden"), CPU sign free agents ON, CPU re-sign players to contract extensions ON, CPU progress players ON, and salary cap OFF.
15. After those changes go back to the top and select "Start Career"
16. Start online league
17. Start the season
18. Select Advance Week, pick sim 10 years. One the achievement pops up for the Vince Lombardi Legacy Award you can hit B to cancel.
