1. are the factory guys just no good?
Both Andreas are, I think, 2nd tier riders - meaning not top 4 and not aliens. Not race winners. Not as long as Marquez, Lorenzo, Rossi and Pedrosa are on factory bikes. Just not going to happen. No disrespect intended, just the truth as I see it. They're missing that last 1/10th of talent.
2. are the factory boys feeling the pressure to do well? (JLO coming and Stoner always in the back of their mind)
Have to be, as much as they say they aren't. They know at least one of them is on the way out, if not both. They have to feel pressure to impress, which can lead to mistakes if they push too much.
3. no problems just cant figure out the tyres?
Tyres are still a variable for everyone - Michelin is still figuring GP out. The tires change every race. From what I read the front gives little feedback, so combine that with pushing too much and a little bit different tyre every race, and you can hit the deck a lot.
4. bad luck?
Dovi for sure.
5. other.
I think Ducati has squandered a lot of opportunities this year to look good. If you look at their history, they are typically close in the beginning of the year and lose touch as the year goes on. They simply don't have the resources to keep up with Honda and Yamaha over the race season. Through some bad luck, mechanical failures and dumb pass attempts they've given away a lot of their opportunities. It just gets harder from here on out. It's good Lorenzo wanted to sign early, because I think if this was around Brno time he'd be less willing to jump ship.
I think Lorenzo will win next year, and I think he'll do it early. If he makes enough points he might be able to squeak the championship. But he needs to maximize the first 3rd of the season.
