what people aren't understanding is that a strong team is necessary to win a tour de france and team riders will sacrifice themselves for the leader of the team, why do you think cadel evans never wins the TDF? because he has been with silence lotto and has an average team, that does little to help his chances.
it is well known that in cycling drafting helps by 10-20% (an arguable figure, but it is definitely a significant amount), any person that has actually watched a cycling race will understand what i mean when teams protect the leader, basically swarming around them in a circle as to provide them with perfect conditions for example drafting slipstream and no wind either side.

any help provided by dopers to team leaders should be nullified by disqualifying the entire team
