I am not sure why people really see this as a 2011 only thing. Since 2009 the wheels have been coming off for Lewis, like a McLaren coming out of the pits at Silverstone, only in slow motion in Lewis' case.
Sure, he has the odd great race, but then he has some that are not so memorable, or remember for all the wrong reasons.
For example, people seem to forget the races towards the end of last season where Alonso scared him off of the road a couple of times and Lewis gave up his position without a real fight. He's had some moments of brain fade this season too with restarts that have hardly been super sharp, but it's not just been this season.
Part of the problem for Lewis is that he is Mr F1 excitement as far as the media are concerned, and he is the soap opera too. There aren't many other drivers who have to put up with this treatment. He looks like he is carrying the F1 world on his shoulders sometimes.
The good news is that his talent will always be there, and I don't think that you can get the yips in F1, but I take you point. For what it's worth, IMHO, I think that all Lewis needs to do is get some perspective and just go about racing like it's all that is important in his life. Rather that thinking about being the most exciting guy in F1, not thinking about being the drive with a pretty pop star for a girlfriend, not thinking that he has to be "the Tiger Woods" of F1 with Puff daddy (or whatever he's called this week) etc in his pit, and all the other guff that he seems to get caught up with.
Just think about driving and driving alone.
For inspiration he just needs to glance over to the other side of his garage and see what his team mate is up to. A man who lives in the exciting world of the Channel Islands and takes part in triathlons in his spare time. Hardly the most exciting life in the world, and I couldn't tell you much about Vettel's life and whether it's any more exciting to be honest, but maybe that's the point.
Drive Lewis, Drive!
