Leap in logic. Lee's had two bad games in around 12 playoff starts the last two years, and using the "his team didn't win the WS argument" is asinine. The Rangers didn't hit at all, so it's not his fault they won the WS (and the second game was a QS and he gave the team a chance to win) in the 2009 WS he single-handedly beat the Yankees twice, so what more did you want from him? Let's keep things in perspective, unless the roster contains 25 Cliff Lee's. By the way, hasn't Beckett gotten rocked the past two post-seasons he's been to while Lee has carried his team into the WS?
Cliff Lee's playoff numbers: 10 GS, 2.13 ERA, 0.81 WHIP, 9.5 K/9, 0.8 BB/9, 10.0 BB/K.
The whole "he's better but Beckett won two WS" argument is full of holes. Lee's the better pitcher in the regular season, post-season, winter leagues, and beer-league softball matchups.
Now don't get me wrong, Beckett can (and should) rebound. He had an extreme case of bad luck with his peripherals (except BB/9) remaining in their usual ranges, but a BABIP near .400, however, at both their bests (performance and health-wise) Lee's the better pitcher and will continue to be the pitcher down the road barring injury.
