Are you talking about the guy who beat Rossi by 100 points in 2007? Or are you talking about the guy who out qualified Rossi by .65 seconds at Donnington, then out qualified Vale by .45 seconds at Laguna, then out qualified Rossi by 1.2 seconds in Brno, and finally he out qualified Rossi by over .5 at Vale's home GP in 2008? Maybe you're talking about the only rider who, when he's on his game, cannot be beaten even by the GOAT?
No matter it's all the same person. He's been around since before this season. Maybe you've heard of him?
Lorenzo is an amazing talent, but he still hasn't achieved anything compared to Stoner. That will hopefully change this season, but Lorenzo has still got to dethrone Stoner as Rossi's nemesis. Stoner might end withdrawing himself from consideration.
