I remember when Pollock came onto the international scene. He was fast! Yes - a tad erratic at times but fast nevertheless.
Later on he bowled 125 or there about. Accurate, yes, and he got wickets but wasn't more exciting than a wall clock.
The most exciting one was Donald because you never knew what you got. One day he destroyed everybody standing and then, truly, I thought nobody is better. The next day he would bowl pies, didn't get his run up right, looked awkward and one would search for the Donald of yesterday. After a while you'd write him off - which would be exactly the time he would bowl a spell that would make the Waugh brothers look like school cricketers. Fast, aggressive and without pity. I loved him - and loved to hate him ....
So Donald for the most exciting bowler - but if I had to choose which one I'd take in my team on day to day bowling performance it would be Steyn
. He has the right mixture of accuracy, aggressiveness, reliability and pace. If you have that the figures will take care of themselves.
