Legitimacy probably depends on who is making the move, who is receiving the move and where the fans sit in terms of the fence of those involved.
From memory, CS' only issue was a couple of moves 'over the back of the circuit' where he felt that he was ridden to the edge of the track (a hard racing move - reference the Doohan/Criville video from Eastern Creek) but he did not labour the point so much although obviously post-race he was fired up about it (unfortunately so IMO as it detracted a lot). That said, he took full blame for the fall with the only talk of a brake check being a journalist trying to get a rise out of CS (He responded 'dont know, ask him' and people ran with it).
Now, that said and done I am somewhat different to many you will debate this with (and will cop plenty of rebuttal from around the traps) but for mine, that was one of Rossi's best races against the 'young turks'. Rossi was sublime and used race craft, mastery and every weapon at his disposal to upset the concentration and race of Stoner, and he did it extremely well which I feel led a lot to Stoner's frustrations.
IMO again but Laguna 2008 should go down as a lesson from an old master and whilst it was hard racing, nothing I saw on TV (watched it at the time and replays since, although not for a few years) overstepped acceptable racing.
Yes CS may feel otherwise and as he was there I happily accept his view but from this armchair spectator's view, it was a race that we so often crave as two hard heads went hammer and tong and yet sadly we look at negatives rather than the spectacle that it was.
FFS, Stoner fell, remounted and did not drop a place such was the mastery of both riders involved ......... awesome.
I will use this another time (not you, but may well be from that side of the fence
)
