I think it was by spring of 2023 it was becoming more obvious that neither Johnson or Rose were going to have a viable future at quarterback.
While of course as fans we can have rose colored glasses that prevent us from seeing reality, after that spring (and particularly once the season started in fall), the writing was on the wall.
Don’t get me wrong, I appreciate that Rose is still with us, and I loved Barnes for what he gave us too. And Johnson had his moments. But none of these guys were going to be the ones that would take us to the promised land so to speak.
