Over at BP, John Perrotto has notes on each team's offseason plans/issues, and has this on the Rangers:
They would be willing to deal anyone from their catching surplus except Taylor Teagarden, meaning that Gerald Laird, Jarrod Saltalamacchia, and Max Ramirez are all available.
I've speculated before that Teagarden is the guy the Rangers would most like to hang onto, but this is the first time I've seen it stated so definitively.
My guess at this point is that Laird ends up dealt for an arm, Max Ramirez starts next season in AAA, and Taylor Teagarden gets the bulk of the catching playing time next year, with Salty backing him up and also playing some DH and maybe some first base while the Rangers see if his bat comes back to life and if Teagarden can stay healthy for a full season.
