I am not so sure of that bit.
For the first one hundred years of Test cricket a four pronged pace attack was almost unheard of. It is West Indies under Lloyd who played four pacers in match after match, series after series and year after year fpr the first time.
Emphasis wrong. The emphasis should have been on the "had at least two all time great fast bowlers" part. The implication being that a great spinner will more often than not help out game balance better than a great quick.
England's problems now don't stem from a lack of spinners or a lack of quicks or a lack of batsmen, but simply from the ones they have not performing at the standard to which their ability suggests they should. I mean why hasn't Monty taken the world by storm like he was threatening to years ago.
They did. Will (Uppercut)'s original post said "Flintoff cannot be all things to England currently" (specifically "to England's bowling-attack), which is true. I pointed-out that virtually no-one could, as the rest of England's team and bowling-attack is simply not good enough. If Flintoff was instead of being Flintoff almost any other player England would still be a moderate-to-poor side.
Unless, just possibly, that someone else was a Donald or Ambrose. A Warne\Murali's addition would quite possibly still mean they lost more than they won. A Donald or Ambrose could just turn them into a pretty decent if not World-beating team.
You seem to have gotten a different interpretation of the conversation than I (and I'm assuming others) certainly did.
Regardless, a Donald or an Ambrose in the place of Flintoff would help a lot less than you might think. Even if it was a direct replacement, a Warne for a Flintoff would be a trade any coach would make without blinking - and it would strengthen the side.
All time Great spinners can bowl all day if necessary, giving them the ability to be adaptive to the conditions much more than quicks. A quick bowler, regardless of how good they are, isn't going to bowl more than around 20 overs in a day - 25 max. A spinner can get through 30+. Given that someone like Warne has a strike rate of around the best quick bowlers, this gives your strike bowler much more opportunity to take wickets.
Also a spinner is much easier to tailor a wicket for without giving your opponent an advantage as well (most of the time), which certainly helps the cause.
