Oh dude! I've been begging EA for the last 5 years to put the Legends in the game! Emails after Emails every year asking for this little feature to be offered.

There was a baseball game a while back that did this. You earn points for achieving certain goals and then Upper Deck allowed for their name to be used. Well you used the points to buy cards.... whatever players or perks were in your pack you got to use in your team.

Made for some of the funnest video game sports ever. I hope EA uses this properly!
