You catch
me and you out a bit on the "but for" argument here, BUT take away Stoner and the scoreboard places second to first, take away Kamikaze Simoncelli and we have an assumption based on the results generally that Pedro would have continued to do well, win races and would not have caused his fragile self any injury of his own design fault or failure.
It is however based on an assumption and not a direct examination of the results sans Stoner and Simoncelli.
We can neither extract or extrapolate results minus any rider nor stretch a long bow and take multiple riders away to achieve a particular position. By stretching that bow far enough Elias is going to take it out in 2011.
Which leads to my next point.
The sans Stoner argument does have a little support in that the Ducati team don't have him and have failed miserably this year.
The sans (name of other rider) argument supporting Pedro's title bid is still a very big hypothetical, he has ridden the Honda factory bike since 2006 and has not taken a title.
No matter how far we stretch the hypothetical bow we have to hit a real world target of a motogp title. If Pedro would have taken it (or be in the lead this year) if Stoner wasn't there shall float eternally in the ether of the great unanswered and only anecdotally supported theories in racing.
Edit: after that I needed an Ellipsis (...) and an emoticon - laying in a hospital bed gives me too much time to make arguments
