Ok, so let me ask you this then (my disagreement with your assessment notwithstanding):
1) Would you be happy rolling with the same OL next year as we did this year? Same 5 starters?
2) Would you be happy with McVay continuing to run the offense the way he did this year, with no deep threat and with a much shorter, condensed passing game that quickly reduced to dink-and-dunk and surrender on 3rd and long with those ridiculous WR screens that go for little if any positive yardage?
Apparently you believe that the only thing we need to do to improve the offense is get rid of Goff, am I right?
That is a super complex question. I believe that if Goff just turned the ball over a few less times, we could still be playing. Yes the defense let us down against GB - but I think QB play was by far the weakest part of the team during the season and different opponents in the playoffs could have had different results - take Green Bay as an example - their offense was unstoppable against us and then mediocre the next week against a (statistically) worse defense. Mostly because of AD IMO - if we don't play Seattle and AD doesn't get hurt, who knows. But this isn't a guarantee and I realize that, just my take.
So for this past year, I think we could have been a Super Bowl team if our QB was above average at turning the ball over.
Moving forward, I expect our defense to be worse - much worse - and the offense needs to pick up the slack.
I believe our OL is a near copy of the Chiefs - so ideally we would get Watson. But that's not realistic.
If we're going to roll with Goff, then we have to upgrade the OL and WRs - but I think the OL and WRs were above average - however, based on my personal assessments of the Rams over the past four years, Goff was a great QB with the best all around supporting cast in the NFL. Whatever happened in the past is done - so if we keep him, we need to get him the best supporting cast, or he's going to keep struggling.
TLDR:
Defense will be worse, offense needs to be much better. Easiest way to do this is moving Goff for Watson, but not likely - if we keep Goff, we need to upgrade both OL and WR or expect Goff to continue to struggle.
My issue with Goff can basically be boiled down to IMO a $34 million QB should win the Super Bowl with the team we have - but that's not productive for what to do going forward.
