I like TD and was hoping he did well this year, BUT…
Wiggins
Kloden
Horner
Vino
VDB
All crashed out. All of them would have been contenders for top 10 at the least. Also maybe Leipheimer, van de Velde and Gesink if they had not suffered injuries. So with a more complete field, Tommy probably would have been out of the top 10, maybe around 15th. Still not bad, but not a major advance from his top 10s in the Vuelta. He has become very consistent, never had a bad stage after stage 1, but other than that I don't see a lot of improvement from those Vueltas. While he did lose time in a crash in stage 1, he also got a lot of it back with the TTT. If you exclude those time differences—IOW, if you consider times after stage 2—it turns out TD’s time was identical to Basso’s. But this was not the Basso of old, and probably not very close to the Basso who dominated the Giro last year.
OTOH, in this year’s Tour, the top 10 were more bunched up. Going back at least to the late 1990s, there has been only one Tour in which the 5th place time and the 10th place time were closer to first than was the case this year. That was 2008 (3:05 vs. 3:57 and 9:05 vs. 10:11), the year Bert and Astana were excluded. So you could argue that a top 10 means a little more now than it did in the past, i.e., that 10th is closer in performance to first. This reduction of the time gaps might be taken as more evidence, I suppose, of a cleaner peloton, if we assume that in the past a few riders were getting a big advantage, either from better programs, or because a substantial number of contenders and/or their domestiques weren’t doping.
In fact, in the LA years, there were usually of course huge gaps from LA to second, and also often from second (Ullrich) to riders further down. If you just remove those two riders from those Tours, the top 10s then look a lot like the top 10 more recently, in terms of time differential. You could say the peloton in the years following 2005 is a lot like the peloton then sans Armstrong/Ullrich,with 2011 continuing that trend a little further.
