Correct me if I'm wrong, but the claim here is that South Africa are the undisputed #1 Test side from 2007-present day?
Not since 2007. At least since late 2008/09 when they won in AUS for the 1st time in history. People seem to forget S Africa have only lost 2 test series since 2006. SRI beat them in 2006 & AUS in 2009 - no test team comes close to this record.
Fact is AUS dynasty ended after the 2006/07 ashes with all those great players leaving.
Just as how the Windies dynasty ended after their 1991 tour to England, although they didn't lose a series until 1995.
Rating every team including AUS started fresh from February 2007, since AUS clearly were never going to be the same again and were going to rebuild and that has been shown pretty conclusively by their performances over the last few years. Unfortunately the ranking system given it just studies form over a 3-year period, didn't consider that Warne, McGrath, Langer, Martyn, Hayden, Gilchrist, MacGill, Gillespie, Kasprowicz, all existed within a year of each other.
So AUS according to the ranking system were still termed # 1 until S Africa beat them in 2008/09.
Then the ranking system some ridiculously penalize S Africa for the lack of activity in the test arena in 2009, since IIRC India ascended to that # 1 status in December after they beat SRI Lanka after heavy activity in 2009.That was madness.
With regards to England the ranking system added up points they attained by winning all of their series (except for the draw in S Africa 2009/10) after that 1-0 loss in the Caribbean 2009. Thus after they defeated AUS in Ashes 10/11 and IND 2011, that were ranked higher than them at the time - that gave them the # 1 tag.
That new ENG team had not won enough series to reach that accolade when they beat india 4-0 last year , since they were only 8 months into their potential dynasty.
Yet when they immediately lost 3-0 to Pakistan in UAE 2012, everyone was saying ENG were not a complete # 1 etc crap - when actually they were never # 1.
English cricket after the Moores/Pietersen saga between West Indies 2009 - Pakistan 2010 where the embryonic stages of the Strauss/Flower partnership and development. No one in their right mind was ranking or speaking of England as anything close to best team in the world then and rightly so because they had a lot players who did not convince the world they good all-round players.
The 2010/11 Ashes win regardless of how far this team goes in the future, will be regarded by historians im sure as the starting point of this teams greatness. Now that they are struggling in Ashes and throughout 2013, you would have to say that teams greatness/peak ended when they won 2-1 in India last year.
That's why the West Indies 76-91 dynasty is always started in 1976 in England and AUS 95-2007 dynasty also begins from the 95 win in the Caribbean.
Players for ENG like Anderson, Tremlett, Cook, Bell, Bresnan came of age in Ashes 2010/11. The faulty ICC ranking system which judges form of the a short two year period, does not recognize this and its has incorrectly made a correlation with ENG of between of WI 09 - PAK 2010 to ENG between AUS 2010/11 - IND 2011. Those are two completely different ENG teams that one cannot compare.
All of this highlights why we need a proper test championship to accurately rank/assess teams, in order to accurately find out who is the # 1.
Surely that's how it should work, beating the #1 side in a series makes you better than them?
Of course not. When New Zealand beat Windies in 1980, that didn't make them the # 1 team in the world.
Neither did Sri Lanka, India or England when they beat AUS in 99, 2001 & 2005.
Some # 1 teams, actually can lose a series in their dynasty and still be the best, you don't have to super invisible like Windies were from 1980-1995, going 15 years without losing a series.
A # 1 test team needs to show longevity and the key ability of being able to win home/away, especially vs big teams over an extended period. IND & ENG # 1 teams never did that and post the AUS 95-2007 undisputed # 1 era team.
S Afirca is real # 1 since that AUS side, because they have done that - only a a win in SRI Lanka is lacking for them in a test record currently.
A record between 2006-2013 which as aforementioned, has seen them lose just two test series.
