On Monday night, Beckham was spotted alongside Cowboys stars Trevon Diggs and Micah Parsons, sitting courtside at the Mavericks-Suns game.
While Beckham played for the Giants during the first five seasons of his career, the Bills and Cowboys stand out.
If he signed with Buffalo, he could catch passes from Josh Allen and take advantage of the spacing that comes with playing alongside Stefon Diggs. The same could be said about Dallas with Dak Prescott and CeeDee Lamb.
There was a time when Beckham was a No. 1 wide receiver, as he recorded more than 1,000 receiving yards in five of his first six seasons.
However, his health is a question mark after he suffered a torn ACL while helping lead the Los Angeles Rams to a Super Bowl LVI win over the Cincinnati Bengals.
Of course, the Dallas faithful were supportive of the receiver, with loud "OBJ" chants breaking out during the game.
Beckham recently made headlines for being removed from a flight in Miami, potentially a cause for concern for some teams. However, it's not a legal situation, and Jerry Jones said that the situation was a non-concern.
