Let's see barry.
Subsequent to the corkscrew incident in 2008 rossi won six races (including the laguna seca race itself obviously) and the world championship; stoner dnfed the next 2 races, but won 2 more races subsequently in 2008 (with scaphoid problems bla bla bla).
In 2009 rossi won 6 races and the world championship and stoner won 4 (with lactose intolerance/cfs bla bla bla) .
In 2010 rossi won 2 races (with broken leg bla bla) and stoner won 3.
In 2011 stoner on a honda won 10 races (probably should have been 12) and rossi on a ducati 0.
This makes a case for the ducati being a pig which held stoner back, and rossi much more so when he got on it as jumkie said but not for the laguna seca 2008 thing negatively affecting rossi and positively affecting stoner.
You know my views on the laguna seca incident and the ducati in general, and perhaps not oddly thay don't put stoner in a bad light and I don't believe laguna seca 08 was any sort of long term mind game defeat, but the sort of specious arguments you run along such lines as in your preceding posts in this thread are what annoy people and damage your credibility in general.
There are ridiculous arguments about stoner and rossi's relative performance on the ducati which are easy to attack, such as the widely promulgated one that any problems rossi had with the ducati are entirely due to the bike, and that as soon as it is fixed he will then pressure stoner into the type of "errors" he made when he was on the ducati, which were as opposed to valentino entirely due to him and not the bike.
