As seen on the official NBA Live Twitter, Patrick Ewing took part in a face scan session for NBA Live 16. It seems likely that we'll see a few other Legends getting their faces scanned for the game.
While it'll be cool to have them in looking more realistic in Ultimate Team, I'm hoping that the Legends presence in NBA Live 16 will extend beyond UT, and that we'll also have Decade All-Stars, or even some historic teams; something playable in other modes.
