When I brought the Hamiltons into things, I was not suggesting they were the only factor. Rather, they are one of several issues which have been mounting up for some time now.
In terms of evidence for the Hamiltons wanting to leave, you've only to look at the Hamilton's track record of attempts to call McLaren's bluff, threats to leave, attempts to actually leave and occasions on which Hamilton Junior has disobeyed the team. The latest reports don't seem all that doubtful when you put them in their proper context.
McLaren do not need this kind of bullpoo, and I'm fed up with seeing Hamilton receive special privileges. I do rate Hamilton very highly as a driver. Ideally, I would like to see McLaren take him down a peg or two or for the Hamiltons to take their heads from their arses, meaning Hamilton could remain at the team. Even with Dennis having completely stepped aside, I still don't envisage a change in this area, however. Whitmarsh, too, gets on well with Hamilton and seems to value him more than he's really worth.
Re. Haug: I've been saying for a long time that NH would be a good choice as team principal. His other involvements could easily be delegated to new talents in wait at Mercedes.
I'd like to see Haug taking. He's the only guy from within McLaren who knows what he's doing, and at the same time he's not really a member of the team
per se. McLaren could get the best of both worlds, whereby somebody cut out for running the team is running the team and the FIA would be slightly placated, with all members of Dennis' era not playing crucial roles in the team.
There would have to be some rejigging of things at Mercedes, but Whitmarsh could hold the fort until Haug could take over; it's not as though 2009 is going to be a vintage season of McLaren, so it's not like he can wreck something else.
One thing is for sure, Whitmarsh's role, or non-role, in this latest fiasco defies all common sense. After being groomed by Dennis for so long and being a man of intellect, there is no excuse for it. If he hasn't picked up such basic management skills by this stage, he never will. Rather than being given more responsibilities, he should be demoted back to his former position as soon as a suitable replacement (i.e. somebody like Haug) is ready to take over.
