Unfortunately, McLaren's laudable and brave decision to go with Honda has (thus far anyway) backfired horribly... it is such a shame to see McLaren struggle so badly, but reverting to a Merc (or Ferrari) customer engine would not only be a humiliating climb down, but would also be more than a mere statement of intent - it would be a virtual guarantee that McLaren would become a permanent second tier team.. a bit like what is happening/has happened to Williams in recent years. McLaren can either double down and go for broke with Honda (possibly literally) or consign themselves to playing second fiddle to one of the 'big boys' for the foreseeable future... frankly, I can't see them going for the latter option and in many ways I hope they don't... and I sincerely hope these lean years of poor performance and (let's face it) downright embarrassment may yet pay off in the long term if they can eventually get back to the top without having to go cap in hand (or at least hand in pocket) to a rival manufacturer.
