I agree with you on Joyer.
He is a bigger risk. His job is to make sure no one gets behind him which he regularly does or jogs along with ball carriers waiting for help instead of just trying to make a tackle.
There has been so many times if he just slowed down the ball carrier someone else would have been able to catch up and help.

Unfortunately waiting for help has been a problem with other players also.

To be fair the aggressive gang tackling was good in the Dallas playoff game.
