I see. I agree that they will likely do a similar job but MA is more potent with the ball and gets it to nibble from a wonderful line and length. And he his metronomic consistency also outshines that of FA. So far I think we have not had much reason to regret his selection as a bowler. Let's see how the Test pans out.
Have to relook if he is really a strike bowler. Same situation in the England tour. No potency after the first spell.
