The England selectors have done well of late. The English media, on the other hand, have gone insane. First Jonathan Trott, who was annointed a Test match number three 'for the next ten years' after two innings against Australia batting at five; now Steven Finn, who, upon taking a few wickets against Bangladesh in favourable conditions, is apparently the next Glenn McGrath. The hype is relentless.
Glenn McGrath? Finn can't even stop falling over, a foible that has caused nothing apart from hilarity in the commentary box and the papers. I don't know much about bowling, but I know one thing: England, with their schedules and their fitness gurus and physiologists, will not be able to resist trying to fix it. And they probably should be trying to fix it: after a while, it won't be funny, and there are a few places where you won't want to keep falling over: it's not got for the physical or mental equilibrium.
But a bowling action is a bit like a golf swing. If you change one bit, all of the other components change too. You can't just reach into it, remove the part you don't like and pop it back in fixed. Finn, like Trott, has some hurdles to clear yet, and it will be easier for them to do that without the man in the street thinking we've found the next McGrath.
