My theory has been that the two rule enforcement changes for 2023 are having a big effect on blocking and offense this season.
For interior linemen the one that would have a direct effect is by not allowing OT to line up so far off the ball that they’re technically in the backfield the guard has to line up closer to the line of scrimmage. Historically, the OT has been allowed to start as an off ball player and guards would line up far enough back off the line of scrimmage to be in the tackle position. By forcing the tackle to move forward onto the line of scrimmage the guard is forced to move forward and therefore has less time between the snap and defender reaching them.
