This is always going to spark some debate.
Wisden must be regarded as the voice of the MCC and therefore, in terms of this, bias towards certain players (W.G.Grace).
Aside from Bradman, Richards and Sobers, I think people will have very different views as to who should, or shouldn't, be in this side.
I grew up as a kid looking at players such as Lara, Warne, Murali, Tendulkar, McGrath, Dravid, Waugh etc... In their respective primes, but I am sure the older, and younger generations would have their opinions.
For example, if you are looking for wicket keepers, Knott over Healy is an interesting one. You also have Jack Russell for pure glove work but if that is not important, and average is, Gilchrist would be a good shout.
