Well if you removed Vettori then it would be 3 out of the top 4. Which is even more interesting. Especially when Mendis and Rashid are 2 of them, although Rashid's batting might have got him some too.
Ajantha Mendis was a pretty big risk to be picked in round 1 but I think that his performances have vindicated the action.
