Career numbers:
regular season: .317 .388 .462 postseason: .314 .384 .479
I wouldn't say losing three percentage points equals ineffectiveness. Granted the post-season number has decreased as he has aged but not to long ago his playoff average was up in the .320 range.
Maybe he doesn't seem as good as others in the payoffs nowadays because he is there so much and he has a much larger sample size?
It's a fair point, and my point isn't (and never was) that Jeter was some horrendous player that falls off the map during the playoffs (historically he's been incredibly clutch). It's also not a point I'm the first to make, but against teams like the Twins in the playoffs, a team without elite starting pitching, guys that rely on off-speed stuff, Jeter is fine, but against teams like Detroit who can roll out hard throwing top end guys each day in a short series, the Yankees big money guys tend to struggle a bit more.
Tex, ARod, Jeter. It's not just Jeter.
If you're team isn't built to bludgeon you to death with big innings, not a big deal. You're not a team that plays for the big inning - you're slapping the ball around and using speed, etc...If you're team is built upon big innings like the Yankees or Phillies tend to be, it becames slightly more concerning in a short series. I guess I may not be explaining it well. Again, it's a point lots of people have made on talk radio as well - it's nothing new, just might be explaining it poorly.
It's also baseball, so it could just be bad luck. Who knows. Maybe Tex and ARod suck in the playoffs because they're chokers, and it's as simple as that. Or they just hit a string of bad match-ups. I mean, Posada looked like a 24 year old in the playoffs last year - can't really explain that away because his bat speed was non-existent most of the year.
