I agree with most of what you say Zainub, and some excellent research here (though the similarities on 'nicknames', cartoons, off-spring etc are somewhat irrelevant, I am sure you will not be surprised to hear!)
Razzaq does have one disadvantage compared to Flintoff, in that he is not a giant of a man; he is a frail looking, medium height, spinach loving chap. Despite this, he is a very powerful hitter indeed, due to that amazing use of the bottom hand; however the difference in physical strength is most telling in his bowling pace; unlike Flintoff, Razzaq does not bowl at 90mph or even 80mph consistently. I fear he will remain a 'support' bowler unless he addresses this, or develops into a very good swing/seam bowler. By no means am I ruling this out, simply sounding a word of caution.
He is one of the most decent, modest and self-effacing chaps in the team though, and that counts for a lot with me.
