Its a bit like when one of the bowlers that comes into the side turns out to be quite handy with the bat gets a fifty odd but disappoints with the ball and goes for 5 an over and no wickets. Latterly, Bresnan was bit a like that. The question is would that bowler get picked again ? Like you, I think they may persevere with him at 6 and hope he improves. In some ways its now a pity theres a rash of limited over stuff where i think he will feature.
