My opinion of him changed after the Championship game with the Saints. He was physically OK to play, but mentally he was in LaLa land. And, last season there were a couple of games that his body language said he wasn't into pass protecting.
When the Rams Zone Blocking scheme is working, EVERY RB for the Rams averages over 3 yards before contact. The Rams don't need a 10-Mil a year RB to score 30 points a game.
I think there's some truth in what you say.
Once again I'll say that I love Gurley but I will agree he has had some issues with his head being in the game. You can see it on the film. Well, to be fair, last year I attributed it to his knee in giving him the benefit of the doubt, but it's there especially early in 2019 where he was just going through the motions compared to later in the season when he was getting more carries. It might have been his knee yes, but...
We also have his behavior at press conferences that was not becoming in a guy who the Rams put forth as a face of the franchise. Something was off with him all season. Maybe he just said "fuck it" because he knew the line was shit. But I agree it goes back to 2018 when CJ was brought in and we saw a brief renaissance in the run game, to include him looking like his old self vs Dallas in the playoffs.
Just my opinion here but IMO Gurley doesn't like sharing the carries. I think he was pissed with CJ's addition and that was part of the reason the Rams kept Brown instead of CJ, because he and Gurley get along. I also think it's why CJ wasn't re-signed mid season when he was available in spite of the fact he knew the offense and could eat carries. And I believe Peete was in his corner and suspect there was some friction with McVay, who is very demanding, which probably had to do with his firing.
Also and btw I don't think we as fans need to have facts to discuss this stuff. We're fans and what we do is share opinions and none of us knows for sure. But either way I believe Gurley being traded will demonstrate that McVay at the least felt he was a distraction behind the scenes in some way. It's gonna hurt too, as he's one of my favorite players.
