Interesting question. So we scrub anyone who has taken a ban and shift everyone else up? So Giro 2010 we can move up 2 for scarponi and basso, 2009 2nd vuelta for valverde, 2008 2 in tdf, 2007 1st in the tdf for contador, 4th in vuelta, 2006 4th but my all time favourite 2005 1st (1999 retro testing) for Basso, Ullrich (retired instead), Mancebo, vinokourov, leipheimer (junior days), rasmussen (where abouts). I know it's a bit of a stretch but its a funny reflection on the sport.
By CQ rankings and ignoring results of anyone with a positive Cadel is hands down best rider of the last 4 years, though I just can't reconcile that with greatest rider of our generation.
Cycling quotient rankings
2010 Rank 5 take out contador 4th.
2009 Rank 3 behind contador and valverde
2008 Rank 3 behind same 2
2007 Rank 1
Then there is still the issue of being clean.
Seriously what is the biggest race that Evans has won? In this we can give him maybe the 2007 TDF, the worlds, what is his next biggest win?
