Tiger has pulled out of next week in Charlotte and the week after at TPC at Sawgrass w/sprained MCL and some other ailment. I think I know what's really going on.
He's finally gonna(or already has) suck it up, get his ego out of the way, call Butch Harmon and ask him for help. I think he finally realizes that Sean Foley's swing-the one where Tiger looks like he's trying to tie his arms into a knot- isn't working. IF he does go back to work with Butch, WATCH OUT at US Open at Congressional. He's won his tournament there before.
I'm no Tiger fan but that's the best move he could make right now.
