Per Nick Underhill: Dennis Allen spoke extensively about the red zone issues. Says it’s a combination of play calls, execution and coaching

I am not going to blame all these problem on Pete Carmichael. All the coaches don't seem to be insync with one another. Two weeks in a roll Offensive line coach not putting their players in position to block for Kamara. On misdirection plays, two defenders running free unblocked and tackled Kamara for a lost. Somewhere, someone is not doing their assignment. Then you have receivers running the same route. Tight ends are not getting open quick enough. It isn't the players, it is ALL the coaches not in sync with each other.
