We talk about there being a big step up in competition while one rises through the levels, be it as a bowler or a batsman. Understandable too, considering the two disciplines are at direct opposition to each other. But what of wicketkeeping? I would assume the parameters for keeping, by and large, stay constant. There can't be much of a difference in standing up or back between cricket levels, since keeping is more a function of one's technique/stamina and general extraneous factors like weather, pitch conditions, mental pressure (?) rather than bowling or batting prowess.
Somewhat similar to umpiring even, then?
