There's a habit in Australian sport to make your best player the captain. It stems from a time before globalisation and the 24-hour news cycle, when the incredible pressure involved in being an elite athlete was at least ocassionally escapable.

We saw with Steve Smith that this pressure takes its toll. We idolise our athletes and sporting mythology to such an extent that the need to win is ingrained into our sporting ethos from an early age.

As a captain, you bare the brunt of this. Now we're not saying that Kerr shouldn't be the Matildas' captain. She's clearly the face of the Matildas regardless and she wears her heart on her sleeve, a trait that enables her to speak the tough truths when the rest of the team need to hear them.

But our reliance on Kerr is beginning to edge into dangerous territory. She's not just the face of Australian football, she's the best player in the Matildas (and one of the best in the world) by some margin.

She's also the captain at 26-years-old and our principal goal threat, a player who spends the majority of her time outside of the general match rhythm, whom we rely on in every game she plays to make the difference.

She's also one our most key defensive assets from set pieces, her physicality and heading ability separating her from many of her teammates. Her physicality is a point as well. Is a player so naturally aggressive and physical the one to always ensure cool heads prevail?

And just in case that wasn't enough, she's also our penalty taker? She has a mixed record from the spot, so if you're looking towards the future and trying to share some of the load among the team, this is the key place to begin.

But the question needs to be asked, whether we can sustainably place all of our hopes on one player's shoulder like this going forward. If you look around the best football teams in the world, the majority don't have their best player as captain. Often, it's one of the least notable players in the team.

Making one of the midfield generals or experienced defensive stalwarts captain - one of the least flashy players on the pitch - re-defines what's valued in the team. It sends a clear message that the team is a unit, individual and equally valued parts of a whole.

It's easy to see why, in a team still to some extent reeling from the fragmentation posed by the Stajcic sacking, the easy decision to make Kerr captain was the right one. Hopefully she can continue to grow into the role, despite the ever-increasing pressures at club and national level.

But in a team that possesses a wealth of talent, yet seems to be beginning to search for other players to take that step up, it might be worth considering other options under Milicic's replacement.
