Nobody is "arguing just to argue". That's something you made up in your brain. Once you know that a QB is never going to be a legitimate starter there's no reason to prolong that experiment. It's time for a different experiment.
What was it that triggered you? This?
How do you qualify "best QB play" exactly? Hoyer did pretty good for a short time. Until opposing D's figured him out. Then it was over.
Or was it this?...........
And the Browns had a terrible OL in front of Couch which led to him shredding his elbow. After that however he was done.
By the times Browns let them both go, both were done.
I mean if you wish to have a discussion on the topic that's just fine. But if you say things you simply can't back up? Don't blame me for it.
