As Danielle Collins walks out to Rod Laver Arena on Saturday night (local time), you may hear a few boos from the Australian Open crowd.

American tennis player Danielle Collins embraced the Australian Open boos after her latest win. But there's more to her heel turn than meets the eye.

Danielle Collins thanked her haters for paying her bills at the Australian Open, and this is the kind of energy more people need to have. As much as athletes probably hope a crowd is for them during matches, it won’t always be that way. Sometimes, fans are for the opposing player, and they let it be known.
