I have always been a fan of the Undertaker. He is a true legend and to be at the top level for as many years as he has, is a great accomplishment. I agree that he is a man of great talent and is one of the greatest 'big men' of all time. He has successed with both the legendary Deadman gimmick, aswell as the biker gimmick, a stark contrast in gimmicks which helped keep him and his character interesting, something which is a necessity in wrestling.
However, there are certain elements of this topic I disagree with. There is no doubt that Undertaker is a great performer, but to say he is "the best in ring competitor in WWE" is a bit over the top. Although he has upped his game in recent months, he has lost a lot of speed and conditioning over the years (as is natural) and the general standard of his matches aren't at the level they were at his peak (which is one again, natural). And that to the fact that there are several very talented wrestlers in WWE currently (Benoit, Edge, Shawn Michaels, etc.), I don't agree with the statement he is the best WWE has to offer.
Also, as much as 'The Streak' is a phenomen in wrestling, given the right opportunity/circumstances, it should be used to put over a future star. Undertaker is a firm believer of putting over new talent to help the business progress once the current headliners have left, so by losing his streak to the 'next big thing' would be the ultimate put over. I firmly believe this should have been the case two years ago when Undertaker faced Orton. That was the time to end the streak (for the record, I don;t believe Batista should be the one to end the streak, he isn't worthy of such an honour).
Also, a big issue I have with 'taker is that he has hardly appeared on Smackdown! over the past couple of years. I know he works a part-time schedule, but if he is going to remain as a main eventer, he needs to be appearing on TV week in, week out. He has been doing this since the Royal Rumble, but this should have been done a long time ago and should continue to be the case until he retires.
Once again, I have nothing but respect for 'taker and am a fan, but he isn't untouchable and immune from critisism.
