Gaz you old goose, of course I agree with you that guys like Smith and whomever else would do better on a factory ride. However, I don't think they'd do better than the current factory guys now.
But we cannot know that without them having the opportunity, thus the perpetual cycle continues
You mention the CHOSEN factory riders. Well why do you think the factories CHOSE them?? Is it because they suck? Did Honda pick Marquez because he was losing races?? Come on man, there are a few exceptions but for the most part, riders are selected because they are superior to other riders.
But how can you tell the superiority if they are not on even machinery ?
You earlier said that the best riders have the best equipment and as such the assumption is that they actually ARE the best riders. You then also seemingly agree that the best machinery allows these riders to demonstrate their higher degree of skills.
Yet, you seemingly cannot also see that the chosen ones are given the better opportunities (equipment) and thus continue to produce results higher than those on lesser equipment. The cycle continues.
As for why they are the chosen ones, well VR, MM, JL etc all had good equipment coming through the ranks and thus were always producing exceptional results which bought them attention and opened doors ........ but when riders on recognised lesser equipment get the doors open people complain of unworthiness.
In addition, in some cases riders may be chosen for marketability reasons for their country or region and as such they may receive an opportunity that another similarly performed rider may not have received
Would you not agree that most of the motogp riders have had similar chances to show their talents while working their way through the lower classes?
Nope, not at all
Jack Miller was on an underperforming bike as an example by comparison to many others against whom he raced. He, along with many has lesser resources (dollars/sponsorship) and as such some opportunities may not arise (in Miller's case, it has risen and yet it is still questioned whilst riders deemed of greater ability struggle in Moto2 for example)
Stoner's bike was not that great in the feeder classes and yet when he eventually produced results that could not be ignored, he was still the third choice of the factory team.
Problem is that the cream only rises to the top if the cream is capable of doing so, and sometimes (IMO) there may well be better or near equal riders not given opportunities.
This is NOT the fault of the factories and nor is it the fault of Rossi (before you suspect), it is the fault of limited opportunities and the sports administrators trying to generate a marketing strategy based around few riders.
Now, I am not suggesting that MotoGP should be a spec series, far from it as for me open slather is the way to go but if we are to look at results and the way in which the chosen are advantaged, look no further back to the last non-Factory win and/or review the podiums over the last 10 years. Again, all IMO but it does not look good for a sport when the chances of winning (with the exception of the remarkable outside the square circumstances) are restricted to 4 bikes with a further 3 that may, only may get there.
