Defense sucks so badly, I don't know what or where the problems lie.  Coaching?  Or lack of talent?  Our outside linebackers look slow.  Or are they out of position?  Our DBs allow receivers to find open fields that you wonder if someone blew an assignment or they are simply confused.  Coaching?  
On offense, replace Dru Brown with Cole McDonald.  Can't have a quarterback running around in the backfield trying to make a play and ends up taking a sack for a huge loss.  It's becoming a pattern.  Just like the O-line making drive-killing penalties.  Mostly, I think, trying to protect Dru.  So take the pressure off and put in a running quarterback.
