Of the 4 majors this year, I think that worlds is the one that brings more players into the picture that could potentially contend than any of the other three. I'm not a "Ricky can't win on wooded courses" guy but I think that courses like those at AO and GCC most specifically play to his biggest strength. He has greater range of putting accuracy than any other player in the game and long open courses put a much bigger premium on putting than on getting off the tee cleanly. When you are throwing 350-500 foot shots into the pin, you accept that you are going to be left with a lot of longer putts to score well.
Wooded courses conversely, put more of a premium on technical placement off the tee than on hitting every 60' putt. I think courses like that at least bring some other styles of play into the conversation. I could see a technician-type player who isn't quite as long like MJ or Sexton getting on to the lead card and making some noise.
Or maybe he'd just throw more forehands off the tee
