I agree. This is the biggest factor to me and exactly why a big part of me wanted to keep Marty around. He has his issues no doubt, just want to make sure I say that because I don't want this to be about him. But the system isn't broken, the players just have to develop better.
The talent is clearly here, it's just getting these guys comfortable in the system enough to be the on same page at all times. I can't tell you how many times I saw guys running routes to the same spot on the field or just looking like they didn't know their assignments. That will improve with a full offseason in the offense, so I don't worry about that too much. But those guys must step up and play better going forward. In the last day or so I went back and broke down the Dallas and Pit games offensively. The amount of times that SSS and Pitta couldn't win against LBs were sickening. The amount of times Flacco had to hold the ball because Wallace and Perriman didn't run good enough routes painted a very clear picture of why this offense struggled. In the Dallas game Pitta was covered by a DE lol. I can't put everything on the coaches.
If you give the offense a quality Center and a strong route runner at WR, I think this offense explodes honestly. I really like Perriman, Waller, Maxx, Dixon, Boyle, and 4/5 of the offensive line moving forward. Given his development and opportunities I think Moore can replace Wallace as a 3rd or 4th option. But like you said guys like Perriman, Waller and Maxx developing will be key.
