I don't see Shak scoring 25 more 100s in next 75-80 games to take over Sober. May be 15 at best, JMG. As for bowling, I don't wanna look too much into it, but his stats already look better than the other 2, though of course things can and will change.
And Kallis not being talked about much doesn't mean anything to me. Being the center of discussion, "the talk," has lot to do with personality and charisma. Kallis doesn't have any popularity. Kallis is a old school, quite guy. He hardly celebrates his wickets or centuries. He played and plays along side with many exciting but less talented players, yet they were more popular among fans.
He did up his rep by getting that wig and people started to talk about it. lol
Same sh¡t, different day.
