Who's the most disappointing team in the Tour?
T-Mobile still deserves a nomination, even though they appear poised to win the team competiton. They've seemed disorganized, they've chased down their own attacks (as even Phil & Paul pointed out), and they could be shut out of a podium finish unless Jan ITT's past Rasmussen.
Liberty Seguros was probably the front-runner, IMO - although the stage win today softens that a bit. Still - a very disappointing ride by Heras, and they have only one rider in the top 20. Certainly, more was expected of them.
