OK, let's start speculating!
Tiger hires his lifelong, best, forever friend ( and sometimes girlfriend facilitator ) as his caddie this week at Firestone, and, I presume next week at the PGA. He is making statements that his knee is feeling great, at long last, and he can walk and play without pain. Should be interesting to see if he has changed his downswing left foot movements that stress the knee. He only has a couple of weeks between stating he could not swing and his first PGA start, so I would not expect him to be competitive. He is sure of 4 competitive rounds this week, last year he finished one up from the bottom in same tourney. This week a guess would be to finish around 40 to 50 percent would be positive, assuming his knee holds up. Making the PGA cut, I say doubtful.
I still believe his goals are to become competitive in '11and win in 2012. Golf misses his ability to just make shots and dominate. I wish him well, and, hope that if he does not achieve his former status, that, it is not due to his knee.
