Mercedes have the ingredients, but they need to make them work. There is massive potential for a multi billion pound, highly skilled highly staffed high profile flop.
McLaren on the other hand seem to be loosing all their key ingredients while trying to put on a brave face. I think its quite telling that both Whitmarsh and now Button have openly said they are struggling. You know that if a team allows its people to say things are bad, then it means things are REALLY bad.
LOL at the barn door comment from Ted about McLaren rear wing. Its huge, and yet Button is still moaning his arse off about rear grip. Hmmm. No mechanical grip?
I'd point out again that I think this was fairly common last year for Button(though also reversed in a few races). Button complained about grip, couldn't set up the car, couldn't decide which way the car needed to go in setup to get better, made a hash of things and did what a rookie does. No grip = put on a huge wing, Hamilton would find balance, settings and just make the car work, so would Alonso, and Vettel. There were a couple races Hamilton went with a bigger wing and Button thought he'd go with a low drag setup, I can't remember if that ever worked.
AS for talking down the team, few if any drivers haven't talked down their chances. Its EASY to talk down chances then win, you talk up your chances and lose and everyone laughs at you. Its why no one at all has proclaimed they have a truly brilliant car this year, no one wants egg on their face in a few races time.
The stupid thing is for Mclaren in terms of going whole new car, surely there are so many car changes next year that essentially tweaking the car into perfection would have taken less time, less money, left more engineers to play around on the 2014 car, and left them a hell of a lot less hassle with the car this season, it seems like a truly demented move from Mclaren. Merc have done a lot by just fixing what wasn't working and seemingly making everything work together very well.
Lastly, on Hamilton I still don't think he remotely moved for the 2014 car alone, he moved because Mclaren are becoming a joke. If Red Bull, Ferrari, maybe even last years Merc or Lotus had that Mclaren car it would have been either winning the title or massively closer, and much closer in the constructors. He left because Mclaren run an overly tight ship, brought on a smarmy little git who was constantly having digs at Hamilton, while screwing up race after race after Hamilton puts it on pole, keeps a lead then they throw it again on a bad strategy or pit stop.
Merc was just the best seat at anyone that wasn't Mclaren, from what almost everyone says, Mclaren are a very strict, boring invasive and work heavy team to drive for, with more media crap than any other team, yet also paying the least in terms of personal sponsors making it stupid. He's getting paid more to have far more time off throughout the year, less commitments to stupid press events, and potentially a team that won't sabotage him.
Keep in mind that he knew where the Mclaren car for this season was probably going by that point in the year and may not have been remotely happy with it, and been given assurances about the Merc car. Ultimately I don't think performance mattered, potential mattered, and a team that wouldn't squander it if they had it was important, but not being at Mclaren this season was for me, his only really major priority.
