It's clear that Brandon Aiyuk and the San Francisco 49ers don't want to be a partnership any longer.

But at the same time, the 'Niners still have Aiyuk under contract, and they don't seem in a hurry to change that.

There isn't any guaranteed money remaining on Aiyuk's contract, so the 49ers can be patient before deciding what their final move is.

It seems unlikely that they could find a trading partner willing to give up an asset for the mercurial Aiyuk and his sizable deal.

Eventually, the 49ers might just have to cut Aiyuk and let him sign elsewhere. 

In the meantime, though, Aiyuk surely isn't thrilled, and earlier this week, he went on his Instagram to express his displeasure.

It was an odd minute-and-a-half video, and we're going to let ESPN's Nick Waggoner explain it via his article on Monday:

Paired with a caption that reads "If you scared just say dat," Aiyuk spent most of the 91 seconds of the video describing an unspecified entity as "little boys" and "female dogs" who are afraid. Aiyuk never explicitly mentions the 49ers by name, but a logical interpretation of the video is that he believes the team is afraid to release him because he could land elsewhere and eventually make it regret letting him go.

Aiyuk starts the video by comparing who he is "dealing with" to kids who don't get picked for a basketball game so they take their ball and go home. He then goes on to say that someone -- presumably, the Niners -- is afraid of how he could come back to haunt them if he plays football elsewhere. He tells that someone to stop running from the bill or belt -- it is hard to tell which of those words Aiyuk uses.
