Last season the Durham Cricket Board insisted that whoever was wicket keeper could not bowl as they were trying to get more full time wicket keepers, for me it meant smaller clubs struggled as generally there wacky was also one of the best bowlers/ fielders!!
For me it was very negative as others never got a chance to keep wicket. at our club it certainly made the team weaker, this rule makes the bigger clubs with large squads even stronger and the smaller teams struggle fact!!!
