Maybe that's the problem? Maybe if QB's had more time to figure it out more would end up successful in the end? I know a lot of youtuber channels like Brett Kollman have contemplated this and think QBs are thrown in way too early and given up on way too quickly.
As far as BY goes, I'm not sold on him or anything, more on the fence. I've seen a lot of good and bad from him. Some QBs do develop late, like Sam Darnold. Do I want to hold onto BY for 5 more years to find out? No. I do think he should be our QB for next year unless a clear and obvious upgrade were to fall into our lap, otherwise I don't see the point of changing QBs going into next year. Keep building the team and insert an upgrade at QB whenever that opportunity presents.
