The two goals that tarnish Alexander's shining Diamonds legacy

In the scheme of an almost nine-year tenure coaching the No. 1 netball side in the world, two goals are nothing. But for departing Australian Diamonds coach Lisa Alexander, two goals will be ranked as blunders among so many triumphs.

One-goal losses in recent World Cup and Commonwealth Games campaigns will remain a blight on such an illustrious career, but Alexander deserves to be remembered and thanked for her tireless work in pushing the boundaries and putting the sport in the position it currently enjoys.

Taking over as Diamonds head coach in 2011, Alexander quickly became one of the best coaches in the world. Maintaining the Diamonds' World No. 1 ranking over her eight-year term, she added a 2014 Commonwealth Games gold medal to the mantel piece, with a 2015 World Cup title following quickly to join her nine Constellation Cup triumphs and five Quad Series titles.

Her incredible record speaks for itself: 102 Tests with 83 wins and 19 losses, including an impressively lopsided record against the Silver Ferns - a 72 percent win rate against her trans-Tasman rivals. It's a record that makes her one of Australia's most successful national coaches.

Alongside her wins were the strong relationships she built with the players and her desire to continue growing and challenging her team.

Throughout her time with the Diamonds, Alexander looked to other codes to learn and further develop her program, including visiting the Wallabies in 2016, sessions with the Australian cricket team and most recently time with England rugby coach Eddie Jones. She was dynamic and knew without experimentation, the Diamonds would stagnate.

Speaking to ESPN during the 2019 World Cup, Alexander wanted her side to continue pushing boundaries and taking risks.

"Perfection is really unattainable ... if you're not really pushing it hard you won't get to improve on what you're doing," she said.

"We've got this mindset that we really want to push the envelope to get better and the only way you do that is actually by taking some risks at different times."

Following the Diamonds' shock one-goal World Cup defeat to the Silver Ferns, the evolution of Alexander continued. Facing the Silver Ferns in Game 2 of the Constellation Cup following a Game 1 loss, she threw out her normal pre-game script and instead looked to poetry and meditation.

Post-match she stated: "I did something different because I wanted to demonstrate to the players that they needed to be brave out there and I had to be brave too."

Her experimentation, however, may have produced her eventual downfall.

While Constellation Cups and Quad Series trophies look great, for the dominant Diamonds, it's all about World Cups and Commonwealth Games. Unfortunately, after a decade of dominance, two silvers isn't good enough.

Entering both tournaments as the red-hot favourites, Alexander first suffered a heart-breaking one-goal loss to the England Roses at the Gold Coast Commonwealth Games. Constant chopping and changing appeared to come back to bite them. Then she again suffered the same fate at the World Cup, this time at the hands of the Silver Ferns. Again her constant line-up changes came into question.

While she got one back on the Silver Ferns with an October Constellation Cup win, it seemed the World Cup loss was the final nail in the coffin of her time at the Diamonds.

Netball Australia announced it is looking to take the side in a new direction and there's an "appetite for change" - despite a year still remaining on Alexander's contract. But with a new four-year cycle beginning, now is the perfect time to farewell one of Australia's best coaches.

Although we won't get the chance to see if Alexander could have taken Australia to another level in an increasingly competitive landscape, the indelible mark she left on netball in Australia won't be forgotten.
