EA SPORTS Madden NFL 25

You can just start a new franchise online/offline using default pre-season rosters and select any team. Once you are at the franchise home tab, go down to Manage Roster -> Free Agents and sign Justin Simmons to your active roster as he is the only 90+ OVR free agent available. Achievement should unlock shortly after signing him.


Edit: As my friend Yaz mentioned below, it is recommended to turn salary cap off before you begin your franchise to ensure the team you are using has enough cap space to sign Simmons.
