Phil has always been great with spectators. He feeds off them. Tiger, on the other hand, feeds the spectators. He doesn't really interact in any meaningful way, he's just grinding along. If he hits a great shot or holes a great putt, he will fire up the crowd at the same time that he's firing himself up. This highlights one of the problems with the pro tour. Too many of them are self-absorbed, ultra-focused grinder type players. There aren't nearly as many smiles and laughs as there ought to be. I know that everybody has to be themselves in order to succeed, but I'd like to see more happy go lucky types out there.
Final point here, the New York crowds are bound and determined to become part of the story. If they become part of the story by siding with Phil and cheering him on and cheering him up during this stressful time, great. It's just a sidebar story, but since it's in New York, it becomes this HUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUGGGGGGGGGGGGGGGGEEEEEEEEEEEEEEE deal.
