I have to agree entirely with nickdnz - I can't understand all this criticism of Deans. As nickdnz points out Deans didn't 'benefit' from the Canterbury system at the Crusaders - he (along with Wayne Smith) built the successful Crusaders system!
When Deans took over Australia at the end of 2007, Australian rugby was hardly in great shape. They had just been knocked out at the quarter-final stage of the Rugby World Cup, and were currently ranked 5th in the World. They had an older squad, and a number of their world class players over the last 10 years were near retirement (e.g Gregan, Larkham, Latham etc). Deans made the decision that the current crop of older players was not going to win him the RWC in 4 years time, so went about introducing new players over the next few years in an attempt to give them a chance of being more competitive at the 2011/2015 Rugby World Cups. In many ways the 2011 Rugby World Cup came a year or two to early for Australia, as their young players weren't quite yet ready for the pressure of a RWC yet. In another 4 years though it could be a very different story! Despite not being quite at their best at the RWC they ended up getting 3rd (much better than last time), they are the current Tri-nations champions, and are currently ranked 2nd in the world on the IRB rankings. Therefore over the last 4 years Deans has manged to introduce a huge number of new players, improved their World Ranking, and improved their result at the Rugby World Cup.
People spend a lot of time pointing out that Deans does not have a great winning percentage as Australian coach. This is true, but his winning percentage is very similar to the other Australian coaches over the last 10 years. In his time as Australian coach
Deans has won 32/55 test matches (58%), which is similar to
John Connelly (16/25 - 64%), and
Eddie Jones (33/57 - 57%). The suggestion that Deans has the 'lowest winning percentage for a Wallaby coach' is completely false - Australia's have won
271/515 (53%) of games that they have played - Deans's winning percentage is actually higher than the average Australian coach!
I'm certainly not suggesting Deans is the greatest coach around - I too get really annoyed by the fanatical Robbie Deans supporters, many of whom vowed to support Australia after Deans lost the AB's coaching position to Henry. Like any coach Deans, certainly does make mistakes - he may have dropped too many experienced players, and kept faith in Quade Cooper a bit too long. I was actually one of those that supported Henry's selection over Deans - not because Deans is not a very good coach, just I though Henry was a better coach, and I thought he would have learnt from his mistakes (which I believe he did). Just because Henry won a Rugby World Cup (on his second attempt, with far more talent to work with) it doesn't mean that Robbie Deans is a poor coach.
Overall I think Deans is a very good coach, and I'd be more than happy if he decided to jump ship and come and coach the AB's now that Henry is gone!
