IMO, this is not the same offense that the team had for the last 12 weeks or so of last season. There was some motion. Beyond that, the read and route scheme was frequently:
- Dak looks at safeties before the snap, decides left or right based on pre-snap read
- Dak looks his decided direction after the snap and has a high/low route scheme on that side of the field. Based on what a defender does, he throws high or low.
I'm not sure I have seen that all year. Everything I have seen is that Dak is going through his read progression after the play starts and his reads cover the entire field. Beyond that, there are few combination routes where one receiver and another are overlapping to force the defense to choose.
I will say this, the read and route scheme that worked so well during the latter 3/4 of last year completely failed against Green Bay because they figured it out and were changing the coverage after the snap. Its what lead to at least one of the INT's and several incompletions. Maybe McCarthy is afraid of that but the current system really sucks.
