I disagree RobTZ
Taking the fact as a given that some of the commentators are correct and Cal was pushed due to his contract in to WSBK instead of Moto 2, I cannot see the benefit of doing that stint, there is no gain and no place from it. Edwards is not leaving. Incidentally I think Edwards will be good on Rossi's bike, even he may take one or two races to settle in and he is in the championship already. They will find someone for the Tech 3 ride, when you know all of the World's riders there will be many who could take that seat. With so many good Yamaha riders they will probably just put it in a safe pair of hands, I would rather it was someone who has done a lot for Yamaha either in endurance or on the roads who gets the seat, it wouldnt damage their careers, not bad to have on their CVs and something to raise their and their Yamaha exploits to a wider audience.
Sykes as you know finished 9th and was sacked in WSBK, yet brilliant as he was for an inexperienced rider without top rides, he had no (major) titles to his name and no experience of the WSBK travelling circus to bring, or draw on when he came to a top seat in WSBK.
Cal has, he has finished top 3 in BSB, has british supersport championship and been part of the WSBK in the supersport class and as we all know won the championship. He isnt a rookie going for the title/good championship finish.
For his career to remain on track he must finish higher in WSBK than his current position, he knows that and has pride in his work. At the moment he is in danger of finishing near where Sykes did, a World champion finishing on the same level as a total rookie- not ideal.
Next season hopefully he has a choice if he finishes high enough, stay in WSBK and if he finishes above a certain position get a tech 3 seat, or go to Moto 2 and if he finishes above a certain position again get a tech 3 or another seat in GP.
I would love to see Edwards give up that seat and do one or two years in WSBK.
Cal knows which will be the best way in for him.
The other riders you mention may already have been on their way to GP, the deal almost done before and the wild card entries were just part of that build up process. The number that may have got a seat due to a wild card entry are so tiny compared to the overall number of riders it just isnt a recognised career path.
Simoncelli for instance has been placed in other series with one off rides but everyone knew where he was destined for. Those rides had nothing to do with his future.
I am in no doubt he has done the right thing.
If anything ruins his future progression it would be finishing 9 or worse in WSBK.
