I think alot of Tendulkars decline can be blamed on mental aspects rather than a huge decline in his physical skills, remember he made his debut at 16...so although he's only 34 he's been playing international cricket, travelling, living out of a suitcase, being under the intense media spotlight, etc for aslong as most international cricketers have at 38-40 years old. He's never really known anything other than international cricket, he was thrust into the limelight before he'd finished school and grew up as a god-like figure under the gaze of millions, surely that has to grind him down sooner or later. He had 14 very good years of international cricket where he achieved everything that could have been expected of him. One has to ask what more he has to achieve in the game ? He's broken/will break just about every batting record in the book and carried the hopes of a nation for more than a decade. I spose he would be playing on in the hope of more consistent performances from his team but that is unlikely to happen during the remainder of his carear.
Have to agree with Richard on Tendulkars heyday being more noteworthy than Pontings, on the basis of the quality of attacks faced. Tendulkar was at his peak at a time when bowling around the globe was still pretty fearsome, Ambrose, Walsh, Donald, Pollock (at his peak), Wasim, Waqar, McGrath, Warne, Murali, Gillespie etc etc...Tendulkar has matchwinning performances to his name against all of them....Pontings done superbly but who are the bowlers he has carved a name for himself against ? Shoaib (inconsistent)...Murali (cant take anything away from that)..Ntini (inconsistent)...Sami (lol)...Zaheer Khan...Pollock (a shadow of the test bowler he once was)...Merv Dillon...Andy Caddick....Harmison (who's had about 10 wonderful tests throught his carear and been trash the rest) etc etc......Clearly stacks up very well in Tendulkars favour...not to take too much away from Ponting as he has been brilliant and chances are he would still have done well if he'd been in this vein of form and maturity in the late 90's...just not as well as he's doing nowdays.
