He said so in his first media interview with the 49ers.

I don’t know the ins and outs of the process - is it a failing by his agent or the front office? Of course you’ll see plenty of comments saying “same old Commanders” because, at face value, it feels a bit Snyder-ish, and I can’t really blame anybody for feeling that way. I also wouldn’t blame Chase for feeling a bit pissed about not hearing from the team directly before the news broke.

If this was a mishandling by the front office, this can’t continue going forward.
