I would go with Kohli and Muller.
True, but it's not like Dolgo and Muller are known for their legendary mental strength or anything.Dolgopolov or Muller. Kohlschreiber will just choke.
Dodig too, but they still have to make it through.Pretty much anyone with a good serve and/or a very agressive game on fire.
Grass is always real fast in Day 1 and 2.
Nobody mentioned Dustin Brown, he'll be very dangerous coming of the qualifying, with already rhytm in the courts.
