Why would Lance comment ? And why would he comment about di Luca ? Why would he comment now ?
Either you believe the blood passport works or you don't. On the positive side you have all the glowing comments from the riders and the UCI board stating that everything has been clean since its introduction, We can now have confidence, the cheats will get caught.
On the other hand, in order to maintain belief you have to subscribe to t concept that Lance was filthy for 7 Tours and then entirely clean on his return, you know, when Brad never rode against him in a Tour, ie you place a tick in the check box for Lance on i)scruples or ii) I can no longer beat the system so for my comeback I will rider clean. Similarly - keeping it topical another rider like Menchov whose departure is rightly greeted with a huge sigh of relief, was able to win the Giro in 2009 and have a number of good wins since the introduction of the Blood Passport. Add in Michael Ashenden's comments are what has changed since 1999 apart from the actors ?
To me Lance's wanted to comment because di Luca testing positive exactly played into his ultimate argument. "All I did was what every body else did for decades before and has been doing since. People just did not like that on this "level" playing field, I was the best ever. di Luca you are an idiot because it is still a modest feat of logistics to beat the tests". He also chose to comment because the main character in the current play on stage was taking the p**s big style AND was not from an English speaking nation and so we would not get all the faux outrage to what he said from the English speaking press, so many of whom have such a guilty conscience to purge with him and would enjoy a chance of attesting to their new-found religion, with a condemnation of their old faith.
To a modest observer one could look at di Luca and say - idiot - did something dumb and was caught, Nibali - take your hat off to the bloke - waltzes around the testers - then goes up the hill like he is fuelled on Nitro, The last time we saw anyone so dominant at the Giro was Basso. Lance we understand you.
Lance is well smart and that was an outstanding comment from him.
