Damian Lillard is known for his incredible ability to score on the basketball court and his immense loyalty to the Portland Trail Blazers.
Lillard is often having fun on social media, so it's no surprise to see him put up a video like this, and the fans' reactions are all also exactly what can be expected in this scenario. Lillard seemed completely locked in in the video, throwing punches with gusto as he tried to win at whatever it is he was doing. They are currently in the middle of a quick rebuild around Lillard while making significant organizational personnel changes and fending off offers for purchase from people like Nike co-founder Phil Knight.
