undoubtedly an increase in pace wud place rasel in the top (even over shahadat i guess). but how do u step up ones pace? I dont think working out day and night helps that explicitly. Timing of delivery is one of the key for speed (without compromising the swing of course). need a specialized pace bowling coach if you ask me. that will not only help rasel but also 'groom' bowlers like waskuruni polash
p.s: outclassing taposh & sharif ?? isnt rasel already ahead with his Grameen phone ad?
