How Don Bradman would Fare In Todays Cricket? We'll never know.
How the current greats like Tendulkar and Lara would've fared in Bradman's era? We'll never know.
Having said that, there's no reason to think Bradman wouldn't be extremely successful in the modern era also. Would he have managed the unbelievable average of 99? Probably not, but that'd still be better than most of the current players, if not all.
As Gowza mentioned in his post, you can't really compare across era's. How'll you compare Alexander's army with Napolean's army?
