The primary reason reported for the voided guaranteed money is Aiyuk's alleged failure to fulfill contractual obligations, specifically by failing to participate in team meetings and other team activities in recent months. The team voided these guarantees back in July, though the news was only recently reported.
49'ers might be doing something unprecedent. If I were Brandon, I'd have done everything to comply. I wonder what type of warnings he was given.
I just have 1 last comment. Please don't end up in Pittsburgh. The Steelers already have an overpaid WR.
