No, in that video Rossi went for the gap and hit Gibernau who was actually driving his normal line. That’s not what just happened; Lorenzo left the door wide open, Marquez went for the inside without touching anyone and then Lorenzo turned into Marquez when he realised it was too late. Completely different matter, Marquez dove in and of course he was never going to make it through that corner following the ideal line, but Lorenzo should’ve defended BEFORE Marquez was ever going to end up next to him.
No, there was nothing wrong with Marquez’ move. He did great.
