I think that is BS . Sure, there are people on here that know their stuff, but you cannot substitute a bit of theory for experience. Your men like Greig obviously understand about the subtle things of the game....he was a progressive, intelligent captain of the type that England have rarely had. That knowledge didnt just stop after he went behind the microphone.
Its one thing posting your opinions on a forum, fairly anonymously, with no real pressure, its another doing so on TV, or for a paper, or for a well read web site such as Cricinfo.
No, we shouldnt worship ex players because they are ex-players, but lets get a bit of perpective on this...probably 0.5% of the people on here have any experience of playing at anything near the standard required to have an understanding of the game in a real competitive level, against other really good players. I am sorry, but some 20 year old, who has played for Crapsville 4ths since he took up the game a couple of years ago, who relies on cricinfo/Wisden almanac for his opinions, and whose first recollection of the game was Harmisons 7 for 11, doesnt quite cut the mustard. And really, this is what this forum is about.
That isnt having a go at those people by the way, its just we have to put those opinions into some sort of perspective and not think that because someone can write 200 words for a match report on the front page that they are the reincanation of Swanton
