Grossi is a tool. His opinion is exactly that - and it carries zero weight with me - he will say anything for attention. Not sure why people think he is football smart.
Baker gets $18M next year, and is a UFA in 2023, right? I understand that normally you want to make the extend / don't extend decision soon so that you do not have a lame duck QB next year on his last year. But they don't have to extend him now. He has one more year on that contract.
Frankly, if I'm Baker, I'm also saying "let's wait until after next season", because I'm sure he is confident that if he gets healthy, he will return to his 2020 levels, which was a top 10 or 12 QB. He would want to bet on himself; then he could get a much better deal. So IMO it is best for both him and the Browns to wait on the decision to extend him, as long as the Browns communicate well to everyone, and don;t leave him hanging.
