Philadelphia 76ers small forward Tobias Harris put on his detective cap on Saturday and caught Dallas Mavericks big man Boban Marjanovic hanging out with Luka Doncic instead of him. Harris and Marjanovic aren't teammates anymore, but that's not stopping the Sixers forward from calling out his so-called best friend for hanging out with someone else.

Both the Sixers and Mavs are staying in the same hotel at Disney World. Marjanovic seemingly had a fun day on Saturday, as he was fishing with Doncic and some of his other Dallas teammates.

Harris and the Sixers went fishing as well on Saturday, but it appears players from separate teams aren't allowed to mingle, something that is clearly going to take Harris time to get used to.

Both the Sixers and Mavs have clinched spots in the 2020 playoffs. Dallas and Philadelphia will use the eight seeding games to knock off the rust before the playoffs begin.

There's a lot of pressure on the Sixers to play well in the postseason, as most NBA pundits believe the franchise will trade either Ben Simmons or Joel Embiid and fire head coach Brett Brown if the team doesn't make a deep playoff run.

As for the Mavs, the franchise is looking to win its first playoff series since the 2011 championship over LeBron James, Dwyane Wade, Chris Bosh, and the rest of the Miami Heat.
