You gone win.Although the wide receiver did not specifically mention Shanahan, the timing of the post, combined with Aiyuks situation, makes this post too coincidental not to be in reference to his recent car accident.Which NFL team Brandon Aiyuk will play for in the 2026 seasonAiyuk has made it clear that he would like to join the Washington Commanders this offseason.The wide receiver would then be able to team up with former 9ers teammate Deebo Samuel.Ian Rapoport admitted the Commanders are concerned about Aiyuks well-being and the idea of signing him remains a long shot.His handling of Shanahans car accident is also unlikely to have impressed the Commanders.The 28-year-old really is not doing himself any favors.Read more:Green Bay Packers financial loss speaks volumes about where the NFL is at right nowThe priceless Jaxson Dart response when a second New York Giants contract is mentionedDeshaun Watson shares training hype video as Browns QB battle with Shedeur Sanders heats up
