I would go so far to say that de Rosa, who started from P12, having a less then perfect get away at the Start, on a kind of slippery Track, was partially the fastest man on the Track, except Cluzel maybe.
Or how do You explain the way he closed up to the Group with all the mighty Yamahas and Mahias?
Well to be completely fair, my recording missed start and first few laps.
I got to watch when he was on P7 1.5-2.0 seconds behind leading group(Cluzel leading with 2+ seconds, then 5 other riders) He almost closed the gap , then made a mistake or others had better exit and back to 1.0 sec+
Then others passed each other multiple times and DeRosa entered the group. From there he could take a few postions bequase of others fighting.
