Sorry man but I disagree with all assessments here.
1. Blythe was actually the best guard per PFF through the first month of last year. Not saying that he doesn't make mistakes or doesn't struggle; everyone struggles, its the NFL. But if you're looking for consistency and continuity, Blythe, and the OLine in general is a good place to start.
2. Havenstien is a mainstay within the LA Rams. He's not going anywhere, nor is he to be replaced as you say within the next year. He's also one of the higher rated RTs among NFL gurus.
3. Joseph-Day may have been blown off the ball a time or two against Carolina, but again, every DLine player has that happen to them. You're saying that it happened almost every time which is way off here. The guy actually took on quite a bit of double teams during the game (no, I didn't count them). He's not going to be some sort of "playmaker" among the others; rather a space eater, which is what the Rams need. Saying he's 'learned nothing' is not the right phrase IMO. When in fact, how could he learn as much as we'd like when he was behind Suh and Smart last season? Lower the expectations on SJD and give him a few games before writing him off.
4. Sit Robey-Coleman? What!? Dude. You can't be serious here... for multiple reasons that don't need explaining.
5. Talib showing his age? In one game, you believe that he's showing his age... ok. While he is older and not the 'shutdown corner he used to be', he's still one of the best in the business. I don't know what more you could ask for as far as production goes.
Again, don't take this response personal... Im just a 180 from you.
