There's a massive difference between being concerned about the state of his game after nearly 18 months away and his first real competitive round and being concerned about his "injuries" and mental issues after the same time period away and only 3 competitive rounds. I'm sure you're intelligent enough to be able to discern the distinctions between the two.
I'll lay it out relatively straight forward for you; if Tiger can not play 3 competitive rounds of golf over the course of two weeks in almost ideal conditions without getting "injured" or "re-injuring" his fragile as tissue paper back, then he has no place on the tour and should not be golfing. Because, that would imply, if we want to be logical about things, that the nerve damage is so severe as to prevent him from training, working out and getting his game back to being in competitive shape.
Fact, Tiger is a mental headcase. Fact, Tiger's stubborn alpha dog personality hates displaying any sort of weakness. Fact, Tiger is rarely honest and straight forward when it comes to being honest about his injuries. Fact, Tiger has never been anything other than hesitant in grinding out rounds with embarrassing scores in order to get his game back in shape. Fact, Tiger sat down for almost an hour of Q&A with sponsors less than 24 hours after withdrawing from Dubai. Fact, Tiger and Notah have talked extensively about the changes in his gym and physical training regimen since the back injury and now all of a sudden he gets back spasms after coming back to competition and knowing he'll have to contend with horrid conditions his next round.
I don't know what to believe from Tiger anymore and I'm not the only one. He's never been very truthful to begin with but his latest episode with the back spasms is outlandish and tough to believe because it flies in the face of everything him and his PR people have been spouting for the past 6-9 months. If you want to be naive and believe that his back spasms stem from a workout gone wrong, go ahead. I don't because it's a convenient excuse and was probably done in mind to spare himself the embarrassment of likely missing two more cuts at the Genesis and Honda.
Tiger's hubris and his pride has been his downfall before and that strikes me as being the case once again. The guy should retire and save us all the dog and pony show. In the meantime, what he does or does not do from here on out isn't my concern. My rooting interest will be with Rory and Rory alone. He should spend some quality time with his family and enjoy life because this isn't worth it. I hope he does, but again, that damn pride and ego of his probably renders that unlikely.
