Raw: JR/King
SD: Josh/Cole/Booker is fine
NXT: Josh/Striker
Superstars: Josh/Striker for SD, Stanford/King for Raw
PPVs: JR/Cole/Booker
EDIT: I decided that while Cole on NXT actually was hilarious stuff, really the show shouldn't be buried like that, so I put the best announce team as far as explaining new characters to the audience on there.
