Call it dumb, but one of the DGP.TV guys I talked to about two weeks before worlds wants to implement this change so that they can help non-DG viewers identify the players. This would include different-colored shirts, names on bags or caddies' shirts, and a bigger buffer between the players/caddies immediately involved and spectators. If they get their way (and player/PDGA buy-in), it's not unthinkable that at a future USDGC (which is among the most spectator and filming-friendly "championship" courses) could have a more golf style atmosphere to it.
