Alijah Arenas also appeared in the starting of the video, smiling as his father opened the suitcase:

"One Day on @firsttake @underdogfantasy sending me Suitcases 🔥🔥🔥 🗣️Thank you guys 🙏🏿," Gilbert Arenas captioned the post.

"One day on First Take. Is this for football season? You know I gotta be Rams, baby. Oh, I hold this box up. The Brook brothers. Okay, now the underdog black skully. Oh, they gave me a ticker. Oh, from Glance. They gave me a little ticker, so I know the score right on the side," Gilbert Arenas was seen saying in the video as he inspected the items.

Underdog, the sports gaming and media company, announced a multi-year contract extension with former Memphis Grizzlies player, Gilbert Arenas' hit show Gil's Arena in January.

The show featured host/executive producer Josiah Johnson, former Sacramento Kings guard Rashad McCants, 2018 NBA Champ Nick Young, one-time NBA All-Star Kenyon Martin, three-time WNBA MVP Sheryl Swoopes, Mr. Basketball USA Brandon Jennings and WNBA champion Lexie Brown.

According to PR Newswire, Gil's Arena gathered more than 500 million views on YouTube, tens of millions of audio downloads and billions of impressions on social media. Gilbert Arenas commented on the partnership:

"Underdog built us a platform and more importantly created a real partnership to share our unfiltered takes with fans. We're building a one-of-a-kind basketball network here, and this is just the beginning – we have big plans for the future," said Arenas.
