For starters we're the worst fielding side in the country and it's unacceptable. We've also only got one consistently good T20 bowler (I'd have said two before this week but Bopara decided not to show up for the last two games).
We're a batsman light but our bowling is so poor in this format that firstly we need to get Amir back, and I'd be tempted to sign another oversees bowler next season to go with him because I can't face another T20 season of Porter and Walter (sorry I don't rate him, he has one good game every five and goes at over 15 an over on a bad game). A Scott Styris clone would be a perfect oversees for us right now. I hear Myburgh is being let go by Somerset at the end of the season, he'd be an ideal signing for us as a limited overs batter who can open or go in the middle order.
Either way we need major surgery in T20 and it's going to take a serious job to fix it.
