What Baseball America thinks

Not that BA, fool. This BA.

Ben Badler at BA.com has a post about catchers and defense.

Certain aspects of catching—agility, footwork, hands, body control—can improve to various degrees, but scouts say that there’s a limit to how much room for growth they feel comfortable projecting a player in different areas. A 19-year-old catcher with a 40 arm on the 20-80 scouting scale might be able to improve his arm strength a tick or two, but he’ll almost never develop a 70 arm. A big, lumbering young catcher might be able to make some strides with his lateral mobility, but he probably won’t get much more agile with age.

There is a table with passed balls, errors, innings, and everything. But, seriously. It's a pretty detailed post.

The catchers are then broken down into The Good and The Bad. An ex-Rattler gets a mention in one of the categories.

Adam Moore: From an offensive standpoint, Moore is one of the better catchers in the minor leagues. The 24-year-old Mariners farmhand hit .319/.396/.506 in 119 games with Double-A West Tenn this season—his second straight year with an OPS above .900—showing a short swing, solid power and a balanced stance that helps him stay back on offspeed stuff. He threw out 36 percent of runners with a strong, accurate arm and a quick release, but his footwork, blocking and receiving have been a constant work-in-progress and he’s not too agile behind the plate. And at 6-foot-3, 220 pounds, Moore is bigger than most catchers, though A.J. Pierzynski and Javy Lopez have had lengthy careers behind the plate at similar sizes.

Moore was a Rattler in 2006.
