Just thinking about it, those Captain knock he plays is why hes in the team. Hes there to bat and what he does best is adapt to the situation. Certainly doesn't need a C next to his name to play those knocks. The captain is there as a strategist not for his ability to play captains knocks.
Very much the case but the reverse is also true. The captain must also perform as a batsman (or bowler for bowling captains). Michael Vaughan and Sourav Ganguly fell by the wayside as captains because they couldn't perform with the bat which held the team back. Fine strategists and fine captains but they couldn't churn it out with the bat. Obviously you don't need to perform like Ricky does but someone like Smith and Fleming who performed decently with the bat and are fairly good captains (actually i rate fleming very highly). But i'm not sticking up for Ponting. He is an ok captain and thats being modest. Good captaincy breeds success but for Ponting it's been the phenomenial players around him that have created such success.
