Woodster
International Captain
Think he will get better as a bowler, the more he understands his role and knows what is expected of him. Although not sure Stuart Broad knows that now.I enjoyed his variations in NZ when he slowed his pace down when conditions suited a bit of swing. Though I agree with you that he'd be more useful as a strike bowler, Rasel with new confidence can bother with the support bowling.
Still think I'd limit Rubel's appearances to the longer format with regards to international cricket.
