Every person who has crossed paths with Kobe Bryant seems to have a story to tell regarding Kobe’s work ethic and competitiveness. Chris Bosh, who won an Olympic gold medal with the Black Mamba in 2008, shared his Mamba moment firsthand on his website. This is the best part:

We went to the village to hang out a few times while the Olympic Games were going on, and I remember everybody walking through the arcade that they’d set up for the athletes. There were a bunch of games, but in particular, they had those mini pop-a-shot basketball games that you can find in just about every arcade in the world. Kobe and Michael Redd started playing, and things got competitive. After a few games, I got tired of watching, so I left to meet up with some friends. I had to have been gone for a couple of hours. When it was almost time to head back to the hotel, I stopped by the arcade again and those guys were still playing! Both of them were in a full sweat with a focus like it was a real game. That was pretty funny to me because I’d always heard about how competitive Kobe was and in that moment, I got to witness it for myself.

In 2008, Redd was playing for the Bucks and averaging 22.7 points per game. Kobe had just lost to the Celtics in the finals and was about to go on a 2009-10 back-to-back title run with the Lakers. But in the summer, during the Olympics, the two locked into an arcade game for hours.

“Both of them were in a full sweat with a focus like it was a real game.”

Imagine the athletes from other countries who walked by these two American basketball players obsessed with the Pop-a-Shot machine.

Kobe continued to dominate Pop-a-Shot years later. He dropped 80-plus on it in 2013 at Twitter’s headquarters.
