Aiyuk has to show up for the first mandatory camp event, otherwise SF will just put him right back on the DNR/LeftTeam list - in which case he will not be counted against the roster, either the 90-man or the 53-man roster come September 1, which would mean SF can void the roster bonus just like they did with his guarantees last year.
As wacky as Aiyuk has apparently been, I just cannot see him putting himself in that situation AGAIN, especially with the possibility looming that he could get to play with JD5. He'll do what he needs to do to make that happen. That means showing up when required to, do what he's asked to do, so SF can't do anything but release him, at latest, by September 1. A September 1 release is the worst-case scenario for Washington, and would probably result, if he is signed then, in Aiyuk just not being very productive this year. If that happens. I'd expect a 2-3 year deal, basically writing off 2026 to get him acclimated and back in football shape.
His agent, however, SHOULD be telling Aiyuk the thing to do is, show up for the OTA workouts starting May 27, and notify the team at the same time that he intends to report on June 9 for the mandatory minicamp. That combination of things could, might, persuade SF to release him with a post-June 1 designation to trigger modest 2026 cap savings. That's the best-case scenario, I think, and really the only way Aiyuk has a decent shot of playing and making any kind of positive impact for the Commanders in 2026-27.
