Steyn maybe a smart cricketer but he is a dumb@ss when it comes to public speaking. This isn't first time he made some stupid comments. Trust me everyone takes Bangladesh seriously, including Steyn. When SA toured BD, steyn was bending his back more than a komlapuri prostitute by the rail road. What he WISHES that he will bowl faster and better, which he will need against stronger opposition than Bangladesh.
This is the same loud mouth who said IPL was a vacation for him. ONly a retard with an IQ below 80 would say something like that in public about a league that is paying his 2nd mortgage.
