I searched the wiki but couldn't find a specific take from a "former NFL coach" on the Aiyuk situation. The wiki doesn't currently reference that source.
Here's what the wiki does say about how the 49ers are handling it (from the Brandon Aiyuk page):
- They voided his contract guarantees and signed Mike Evans, signaling they're moving on.
- GM John Lynch said at the combine a split is inevitable: "nothing will happen until the new league year starts, and then when it happens – kinda semantics."
- As of late June, ESPN's Jeremy Fowler reported Aiyuk is "essentially untradeable right now" — he hasn't filed for reinstatement, so the 49ers can't even release him yet. Once he does, the expected path is Aiyuk reports to camp, forcing the 49ers to release him due to injury liability (over $26M).
If you remember which former NFL coach gave the take (e.g., a specific analyst or show), let me know and I can search more specifically.
