If anyone, and why?
If I was Rahul Dravid, I would retire the day after I got my average up to 60, he's at 58.75 now...he can get there if he bats selfishly for a couple tests.
But then I'm a selfish bastard.
IMO Dravid and Ponting have the best chance. Tendulkar is winding down, and I don't think Yousuf has the class to sustain it at that level. Kallis is an X factor, but he too is probably winding down soon.
Though in all honesty, I don't think anyone of them will do it.
