In my opinion, I see Valverde as overrated. He is actually similiar to Cunego in terms of an excellent 1 day rider, but he is a little bit more solid as a stage race rider.
Before everyone talks about Cunego's Giro win, lets examine that win. The 2004 Top 10 was one of the weakest Top 10 I have ever seen. Remember, that Bradley McGee Finished in the Top 10 of that Giro. A Prologue specialist finished Top 10... The only real competition he had was no competition because it was Simoni who was his teammate. The day he went back into pink with the 70 km escape around stage 15 (I dont remember the stage number), nobody chased him because they knew as soon as they got close, Gilberto was going take off.
1. Damieno Cunego
2. Serguei Gonchar- Only time ever competed for podium was in the Giro. He was consistent, but that was due to his TT skills.
3. Gilberto Simoni- His teammate, so was forced to play defensive
4. Dario Cioni- This to my memory was his highest finish in a Grant Tour, and I believe his only time in the Top 5.
5. Yaroslav Popovych- Has 1 podium finish in a Grand Tour which was the previous year Giro. I believe this was his last Top 10 finish in a Grand Tour.
6. Stefano Garzelli- Only winner of the a Grand Tour before and after in this Top 10 that was not on Cunego's team.
7. Wladimir Belli- Similiar to Gonchar in terms of a consistent Top 10. Maybe one podium finish in a Grand Tour, not including the Giro the one he was kicked out while in 3rd.
8. Bradley McGee- By far his best finish in a Grand Tour (Well maybe he had close to this type of finish in a Vuelta). This was the performance of the year to me, he completely rode out of his body to stay in this position.
9. Tadej Valijavec- Again a consistent 8th-12th place finisher, nothing more, nothing less.
10. Juan Manual Garate- Memory serves me correct, no podiums, and i dont think he has ever finished in a Top 5.
IN fact the only other Grand Tour podium finishers that even finished this race was a 40 year old Pavel Tonkov, Eddy Mazzoleni, and Marzio Bruseghin. This was an unusual Giro in terms of the smaller number of climbing stages (this was the Giro Petacchi won 9 stages). ONly 3 Mountaintop Finishes, and the only one that was more then 6 percent gradient as a finish was Bormio 2000.
Cunego was on great form with the right course at the time right time. THe man earned his victory, but the expectation thrown upon him was beyond his capabilities. The reason for the hype was this giro was 3 months after the death of Pantani, so the tifiosi was wanting to find the next Marco, and Cunego was the guy who received that spotlight. HE still is young, so if starts to put his focus on stage wins instead of overall, and go for the Classics, he can turn out to be 1 of the greatest Classics riders, but he has missed out on multiple Ardennes Classics because he was aiming his form at the Giro instead of 3 weeks earlier.
