The Open can be unpredictable. The weather can change -- sunny one minute, sideways rain the next. Add in the unknown with this Open: The oldest major is at Royal Portrush for the first time in 68 years. So, aside from a few locals who grew up around these links -- Rory McIlroy, Graeme McDowell, Darren Clarke and Brooks Koepka's caddie, Ricky Elliott -- almost the entire field comes in with little knowledge of the venue.
So what will happen? Our experts take their swings.

Open champion: Tommy Fleetwood
Why he'll win: I'm not getting suckered in to the "home course" narrative when it comes to Rory McIlroy.
