That's a very valid point, that I'm new here and coming into an ongoing argument. I can imagine it is frustrating, to be making the same points over and over again.
I must say, I agree with a lot of your post here to be honest. The bit about other players on the team and coaching playing a huge aspect for - not just QBs - but any player. Coaching in particular. Take someone like Alex Smith - I know I'll be torn apart for saying it, but I've always felt he has been kinda unlucky. Didn't he have a new OC every year in SF? I might be wrong on that, but it felt like it. So every year, he had to learn a new offense. Then when he gets some stability and good coaching, he can show he's a pretty good QB. OK, he's not elite. But he's not as much of a bust as some people label him.
I've often wondered about the busts, the high profile players - I guess QBs for the most part, and how would they have done with a different franchise, better coach? It's an intriguing argument.
It would certainly be nice if the FO could put a good, consistent team together, and the staff could coach them well, and call good plays, set good schemes.
Am I confident it'll happen? Personally, I'm not. Not with Tannenbum in charge, not with his history, and not with the amount of money he's tied into underperforming players.
