Why Attack Armstrong?

Well i think armstrong is doing what he is doing to take the pressure off contador until contador takes the lead in the mountains then the other 4 leaders of astana can protect him. secondly why hasn't kloden ever gone somewhere to be a team leader i understand that u need a strong team but look at columbia surely they wud be happy to lead him to the grand tours. can anybody tell me a good website to stay in touch with th pro tour season?
