2) The reason is they need to spend cash to achieve the 89%
The narrative that they paid JB that much or the even more ridiculous take that they "overpaid" Hoyer to reach that is so silly. They have a couple good players on their roster they could extend at any point a bit ahead of time just to hit the floor. There is no need to throw out cash on two backup level QBs.
The main reason I liked Hoyer as a backup QB here is because he cost us nothing.
