Wow, I thought you observed MotoGP. I didn't think you were such a shallow observer. It is surprising to me that you would admit on this forum that you are unable to determine if a rider is thinking about their strategy in a race or that perhaps you think all the riders line up on the grid with out one.
I also thought you read MotoMatters where Krop who from my observations knows a .... load more about the sport than you and I and actually sits across from the riders and asks them direct questions as well as doing the same to many paddock insiders. Seeing as though you don't read and or analyse the sport I will bring you up to speed. Krop has stated categorically that Sic is not very intelligent.
So based on the respected opinion of an insider and my observations of racing tactics I think it is a fair assumption that Sic was not overly intelligent and didn't have the mental capacity to win a championship against the greatest riders at the pinnacle of the sport. There is also sufficient precedent to suggest that minor class titles does not automatically conclude that skill and mental capacity is sufficient for premier class success.
... So in a nut shell why don't you pull your hypocritical head out of your arse.
Mental, I know you were replying to Rog, however, I think I'll give a bit of input here if I may. It’s an interesting way you closed your post. Reminds me of Bunyip's rant where he starts off point the "hypocrisy" of people's personal reflections regarding Sic (as if anybody can assess this from afar), then says, but don't "castigate me" for expressing my feeling on Sic's death. That should have made most pause at the depth of misconnection.
Now calling out Roger because he can't read minds of the riders? I admit right now then too, that I cannot determine what the riders are thinking either regarding their strategies, and if you can, you are a much better man than me. Almost reminds me of a member who claimed he could detect the level of TC from watching beyond the fence at the track. I've heard riders explicitly state that they are unsure of their strategy for a race and may just develop one on the fly as events unfold during the race itself.
Regarding Marco's intelligence, I suppose there is a spectrum. Do I think he was as smart as a rocket scientist, probably not, but then again, most rocket scientists couldn't ride a GP bike like Marco either. In reflection, do I think he was unintelligent enough, no. I really can't determine where he would have ranked in IQ test among his 17 peers. He sounded funny in English, but I probably would sound pretty dumb in Italian.
Citing Kropo, assuming he stated, "categorically that Sic was not very intelligent" would also give me pause to ponder just how accurate was his assessment. Kropo is still human right? So I’ll assume he is fallible. I don't quite remember Kropo being as adamant as you say, but I could be wrong. Maybe a link would help clarify his opinion of the man's intelligence. Or we could just ask him, as he stated, he has no problem being honest about the dead. Though I wouldn’t use his respected opinion as an ATM machine to make a water tight case about somebody’s intelligence as he had only met the man a very few times (that I do remember him saying).
I'm not going to touch the argument that Sic could have or not won a premier class title, as I'd rather not engage in a debate that I would characterize in the way you closed your above post.
