oh more than 1 absolutely, consensus is and A, B, and a C (the last being someone who can, but it is not their primary/desired position).Back in 14U, when the #2 catcher "Hissy quits" on Saturday and DD had to catch 5 back to back games in row on Sunday, you realize that having more than 1 catcher is kind of important.
but if you had 5 on the roster, who all wanted plate time, its gonna get interesting.
funny, 1B catcher on DDs team (DD was 1A) was getting about 40% of the innings behind the plate. left team because she was not getting enough plate time. now is looking for pickup opportunities, presumably because current team is not giving her 90% plus plate time, on a team that is not even close to as good. it is not always greener.
