It sure looked like it in the first few games. All them busted coverages is a sign of something.
Meh. when a RB bursts through the line and players are jogging to the ball or even worse standing around watching, that's not scheme confusion.
Fans love to exaggerate on the topic of players not hustling.
It has not been a major problem from my reviews of games.
It has happened occasionally but nothing close to what many fans claim.
On the other hand, player confusion and poor angles has been a huge problem.
Dontari Poe is the primary player that often appears to just be going through the motions; however, I think he is just not in good enough condition to do much more than he has been doing. Also they played him for 79% of the defensive snaps in the Browns game which is far more than many "in their prime" NT types play.
There have been snaps where Aldon Smith didn't appear to be going 100% but I think he just gets gassed at times. He played 84% in the Giants game and has averaged about 80% which is more than DLaw averaged in his best season or any season. That's crazy considering that Aldon Smith has not played in 5 years. I expected him to be a designated pass rusher that played about 40%. In 2018 Randy Gregory was a designed pass rusher and played 45% of the snaps.
There was one play that fans focused on with regards to Jaylon "just jogging". After reviewing that play from multiple angles on the coaches film, it was obvious that Jaylon lost track of which player had the ball and he thought the ball carrier had been tackled. Joe Thomas had basically tackled (push out of bounds) a player that did not have the ball and Jaylon was watching Thomas contact that player. Jaylon had let up but then started running once he saw the actual ball carrier (OBJ). Jaylon then chased him and almost caught him. If a player was "just jogging" why would he then go max effort to chase down a smaller/faster player? That would just be making more work for himself.
It would be dumb for players to expend more energy than needed. Emmitt said a few years ago that Zeke needs to go out of bounds on occasion instead of struggle for 1 extra yard, especially on plays where he already has the 1st down.
