if cav joins sky then wiggins will be looking for a new team - cant see that my self
i see wiggins doing a cadel - he crashed out last year due to wrong place wrong time and won this year - ill put money on wiggins next year tbh - would love to see him give the schlecks a kicking .... if cadel has any sense he would retire at the top of his game - he was the best on the 3 weeks of the tour this year BUT i am not under any illusion that he is the best in the peloton.....
also cav becoming more self reliant like hushovd - i dont think so, i dont think mentally he can hold together - when things go south he seems to go south too - only my opinion though
