hitting, throwing, blocking and game management hold more weight. A catcher isn't going to be recruited primarily on his receiving skills. It matters but tertiary at best.A big key here is preventing runners from advancing bases. Of course, a past ball is a free base. A stolen base is advancing a base. A well-framed pitch may, on occasion, get you a strike or, less frequently, an out but is relatively less of a factor in preventing bases. You can argue, situationally, between the importance of blocking vs. throwing/POP but receiving is a clear third at that level, even with the abstract deductions that can be made with buying occasional strikes.
Thanks for your reply, @cabbagedad. When you say game management... are you including pitch calling in that?
