There's nothing to dismiss in that "argument", there's just nothing in it. I've given evidence of what MM could have felt aggrieved about, confirmed by Alzamora.
Not if MM put himself between both on purpose, which is what's the point of the discussion here. Rossi was faster than Lorenzo in PI and only finished behind JLo because of MM. Both VR and AI were much faster than JL there. Sepang was different, most likely VR actually got 3 extra points there thanks to Marquez, but got the penalty too. Valencia was the other big blow, where MM refused to pass JL, against his own and his team's interests. VR lost the title because of PI and Valencia. In PI he should have gained 3 points on Lorenzo, but lost 7. In Valencia he should have lost 3 points to Lorenzo by Lorenzo being 3rd and Rossi 4th (worst case scenario) but lost 12. That made the difference.
So no, Rossi was not just racing Lorenzo. That's the whole problem actually.
And please, stop this "MM won in PI therefore he did not interfere" crap. He did interfere but, at the time, he did not see it necessary to concede the race win because of his massive pace advantage there. His work cost VR a net change of -10 points! If he did that in one more race that was it, job done, which he did at Valencia.
2006 has nothing to do with 2015. VR uncharacteristically crashed and lost the title. Full stop. Did he ever complain or come up with any ........? No. He lost it fair and square without any wrongdoing by anyone. Elias was riding hard for his own interests as he was expected to do.
