The asked Alec Stewart for 2007 but he turned them down, then they'd have had the full set of Bowler, batsman, wicketkeeper. Sadly Geraint Jones was playing abroad, Chris Read was off with the ICL, Jack Russell was off with the commentary team and every other keeper in the country was either not well known enough or playing for England.
If they still fancy completing the set, one of the above?
Or maybe Graeme Swann, Chris Tremlett, etc. Ooh, Shane Warne! He'd probably try and get it one with every female on the show but might be quite good.
