By using the criteria from 06-014, your refining this too narrow. If you include players who played a full career, with some of those years falling in the same era, yet not the entire era, your not going to get much in return. Keep in mind,
your also asking for Offense numbers only, which I would say, you should also be looking at any Catcher's Defensive skills, as importantly if not moreso important in respect to the position.
Offensively:
NL- You already have Posey and Molina. Add McCann, and In the same era's eclipsing across those years, you have the Buc's prior catcher, Kendall.
AL: Mauer, Pierzynski, Posada, and Avila, now how about Salvador Perez? or-Wieters?
***If you want to look at Defense as well, which IS essential despite your insistence to make your point on Offense only.....,hell, I'll give you that much for Offense, less those noted.
BUT- you can't define a Catcher by OFFENSE ONLY: but then you already know as much. Is this only about offense only to prove Martin's worth, cuz if it is, then its a lopsided look at Catcher's wouldn't you say? Without any respect to a back-stops job?
Ya' gotta' have a solid backstop, and all these Active Catchers have outperformed Mar-tan defensively: (one reason IMHO, the Bums didn't re-sign him): -
Snyder
Ianetta
Pierzynski
Ruiz
Avila
Hanigan
Y. Molina
J. Molina
Torrealba
Lucroy
Suzuki
Soto and even believe it or not
V-Mart
All have active better defensive fielding percentages than R. Mar-tan, who ranks #16 on the Active Fielding Pctg. of Catchers....but you don't want a defensive stat, why NOT????? (only to prove a point via offense only).....? REF: *** para: noted aboveThat's 3/4ths of a Catcher's Function. Another reason Russell wasn't re-signed IMO in L.A. he had a helluva time throwing anyone out. You want those numbers too? (But like I said, the Teacher doesn't allow others to do your homework) .... LOL...
