Even in county cricket, there is a phobia of keepers who bat below 7 - Kulli rightly mentions Michael Bates, and I would also mention Andy Hodd, Colin Metson, Graham Kersey and I'm sure a few others. You even have counties converting batsmen into keepers, as Yorkshire have with Jonny Tattersall. It becomes compulsive-- even when England played six batsmen and had Bresnan, Swann and a pre-face-lift Broad amongst the bowlers, they went batsman rather than gloveman.
