Jays catchers were 14th in WAR. We can talk about framing, but the data currently isn't refined enough (imo) to be useful for direct comparison between players or teams. I would peg its current usefulness at saying one catcher is likely above average or another is below average, but not as a ranking system or in terms of adding or deducting WAR.
I would prefer to pick up Martin obviously, or several other guys, but I'm much more worried about LF and 2nd base.
