I think we've come full circle. Jeter is considered clutch. A-Rod is considered choke. There is very little difference between their post-season averages(Jeter higher BA, A-Rod higher SLG, OBP almost the same). Who do fans, coaches, teammates want at the plate in the 9th inning of a WS game?
To take it a bit further, neither would be considered the Yanks biggest threat these days. I'd say it's Granderson or Cano. Granderson, with limited experience(121 PA), is pretty close in AVG/OBP/SLG to Jeter/A-Rod. Cano stinks it up a bit in 176 post-season PA. Of the four, who do most people want batting? Jeter over A-Rod is easy. Then you could start with lefty/righty with the other three. Or maybe situational(need a homer, a hit or a baserunner). I'm sure I'm biased but, for a generic late-inning pressure AB, I take Jeter. Is he clutch or do I just think that way? More importantly, does he think that way?
