Ausmus was more than just a defensive catcher, even when those comments happened in 2007. He just wasn't a home run masher during the steroid era, so he was devalued. Were you a fan before the mid-00s? SS has always been awful. Much worse than catcher on most of our playoff teams. I will say that ****ie Thon had potential to be the best SS in history if not for being beaned in the 80s. Sad one there. I'd say Alan Ashby was a pretty good catcher too, but that's going too far back.
Ausmus's career slash line is .251/.325/.344 - probably the 6th best batter on the team as constructed today. He just didn't hit HRs. Ausmus (our best C) had a career offensive WAR of 8.6. Adam Everett (our best SS that spent a majority of a career here) was a .7 for his career.
Neither has been a position of strength for us historically like some others, so we are arguing details. These two positions have been awful. 2B, CF, LF, and 1B have historically been our best positions by far. RF pretty good, then 3B decent with Ensberg/Caminiti in the last few decades.
SS and C are way behind, an I say SS has been much much worse. SS probably feels worse too because of the top-quality players you routinely see there. We have had to see Larkin, Ripken, A-Rod, Jeter, Vizquel, Garciaparra, etc. all be great players. Then the next level with people like Edgar Renteria were killing us too while we were trotting out junk. Catcher is much more limited - Pudge, Piazza, Molina, Varitek... Maybe Mauer. I am probably missing one.
