Taufel played a big part.
OMG! All Pakistanis really p!ssed off so are blaming the umpire. I was watching the match and none of the 20 or so lbws that Pakistan appealed for were not out. Most of the time the ball pitched outside the line or was going away. The only time the umpires were wrong was when Umar Akmal got given lbw when in fact it hit his bat. But even though that was the wrong decision, you have to consider how he was playing a sweep shot and when he made contact with the ball, the bat was pointing toward the umpires. A deflection onto the pads it was, but for the umpire the ball hit him straight onto the pads simply because of the position he was in with with relation to the direction the bat was pointing (slightly confusing i know).
Blame the Pakistani fielding. If Younis Khan hadn't dropped that regulation catch and got Elliot (who made the most runs) out, then Pakistan would be in tomorrows final, not New Zealand.
All umpires, no matter how good, only see it once and form one angle and need 1 second to decide the fate of the batsman. They don't see it through hawk eye and the side angle and in slow motion like we do.
