Is there any good evidence that Stoner's emotions or supposed "mental weakness" has had any effect whatsoever on Stoner's performance on track?
I think the "emotional" thing was a barb thrown by Rossi and repeated ad nauseum by his flock, to the extent that now even some Stoner fans seem to accept it exists. But think about it, is there any real evidence? (And yeah, I remember him binning it twice immediately after Laguna, but as you've argued yourself - and I happen to agree - he was rightly in a "win it or bin it" mode, which was necessary to win the championship at that point. Even this period was over two years ago.)
I do agree however that it's Rossi attempting to pull the strings and Stoner who's replying.
EDIT: btw, perhaps it was Stoner's remark about Rossi "getting his arse kicked by a guy on the same bike" that lead to last week's battle....
