You can edit the player names in the PGA TOUR field, to those of the real life TOUR. The problem will be trying to figure out which fictional player would best translate to which TOUR pro. I'm sure there will be some community guidelines posted shortly after release to help players with this. HB Studios can't be seen as helping to facilitate that because it would no doubt be seen as unauthorized by the PGA TOUR.
Here's something to keep in mind, you won't ever see these players actually playing in the tournament, along side you... even as nothing more than a ghost ball. The benefit of that is you won't have to worry about getting their likenesses right, for authenticity. The reason I've never enjoyed career mode is because you wind up playing a spread sheet of invisible players. Their scores a derived from statistical formulas, not a attribute based recreation of a particular player, playing out the round, stroke by stroke as an AI player.
