I'm optimistic about him...he might not be ready for limited overs cricket just yet...he seems to get hit for sixes way too much, but seems to follow up well but getting wickets after being smacked (3x in this tourney). His ODI strike rate is good but not great. If he is a better Test bowler, than I don't mind letting him cut his teeth at Test level given that NONE of our pacers has a strike rate under 100 in that format. That is piss poor...Chamu Chibabha would be ashamed.
Also you can't conclude he can't bowl with an old ball because in ODIs the oldest a ball will be is 25 overs old, not old enough for reverse and not new enough to generate bounce or prodigious swing. He's done well enough in this tournament to keep his reputation intact, if not exactly enhanced.
Cricket cannot live with the mistaken belief that people want to see big hits. People like to see goals, but no one is talking of moving the goalposts a metre wider either side. (Harsha Bhogle)
