The problem I have with this is that I keep picturing Mickelson as the anonymous source, and he has ulterior motives. Though I suppose it could have been Spieth, Thomas, or Fowler speaking in retaliation for Reed's comments from the day before.
It's not Tiger, unless he speaks about himself in the 3rd person. I be shocked if Webb or Finau would get involved in the fray, and Watson would be strange b/c he's a poor team golfer himself. Dechambeau I could see because he is brash, but after the 0-3 performance he'd be best to shut up. And Koepka and Johnson were too busy fighting each other and hate the media too much to comment.
