See my analysis under basic Giro thread on why Chechu did what he did. There was significant strategic value to DC as a team from his actions.
Not necessarily anticipated (but perhaps so, given how cunning Bruyneel and Yates are), but a "gift" that resulted in part from the weather conditions, was Paolo gained the following time on significant rivals, as another poster mentioned. What a great outcome for DC!!!
Cunego 7 seconds
Diluca same
Basso same
Simoni 23 seconds --> Now 49 seconds behind Il Falco on GC after only three stages
Rujano 49 seconds (as mentioned by another poster) --> Now 1'28 down from Il Falco
The times on Simoni and Rujano are significant. And, frankly, every second counts (no pun intended!)
I think DC should be very very happy with this stage, even though they lost the maglia rosa. Paolo had said after Stage 1 that they wouldn't necessarily defend it. Plus, Gerolsteiner works tomorrow.
DC has done everything perfectly so far. The time they have on each of the key GC rivals is probably more than they could have hoped for, before the race, even under the "best case" scenario. That is particularly the case on Simoni and Rujano. If Rujano loses another 2' to 3' to DC on the TTT, he would be 3'-5' minutes behind Il Falco with two ITTs to go. Not a good outcome.
