In general, I think that owners are very concerned with A+++ armed catchers. My very first piece of advice to a newbie would be to draft one. If I figure to be in a league with a lot of those unoriginal, cookie cutter, copy and paste, switch hitting, speedy, high average, singles hitting teams in pitcher parks, I'd definitely draft one. So yeah, I feel strongly on the importance of such a catcher. But I would also suggest to not pigeonhole oneself as there are many ways to win at sim baseball and several of those ways are more cost effective. There aren't many good deals on catchers with the A+ arms except for the ones whose secondary position is catcher.
