I'd say the evidence based on draft selections, types of FAs, OC hires, and in-game decisions/playcalling strongly suggest that the offense is basically what he wants. He may want it to be more successful, but assembling an all rookie/career backup line pretty much guaranteed that the season would be a struggle. Keeping on keeping on starting Britt, Cook, and Co after a few years of evidence they are mostly depth players had a hand in this as well.
I have to admit the talk of Washington, former Titan QBs used as evidence of Fisher's coaching talent, and so on strikes me as completely irrelevant. Washington didn't draft bupkis for years because we fleeced them and they won the division. Yeah they played in a weaker division. So what, they didn't have many draft picks. It's a wash to me. Steve McNair was a QB from long ago in a game that's played differently from today on a team that's not ours. I don't see how that applies to Fisher today. We should be arguing the merits of his tenure as a Ram coach. 4 years, 4 losers. I'm trying to see all points of view, but I admit to complete confusion as to why anyone would want to stay this course. God knows I don't know any more than anyone else here about football, but this confuses me.
