Beason has missed a few tackles and assignments (it appears) but I don't think that this is a reason to move him for the remainder of the season. If he returns 100% healthy, he goes back in the middle. We need our best LB'ers on the field.
We do need our best current MLB to be playing the spot. I don't believe that Beason is currently our best MLB.
Honestly the idea that he's going to come back 100% healthy after being banged up like he has all year after one off week is a pipe dream. Not only is he clearly still struggling with recovery from his injury last year but how he has a shoulder injury that has lead him to tackle terribly. Beason this year is not the Beason everyone wants back in the middle and this small amount of time is not likely to bring him back.
Kuechly made his first start at MLB and played his fuging balls off. I know every coach likes to say you can't lose your job to an injury but when the backup is a 9th overall future superstar in this league who is already balling? Maybe you can lose your job to that injury...
