I had some down time today.  I took a look at our UK game Freak posted.  I looked at UK's 3 scoring plays in the 1st half.  Our defense is having troubles for same or similar issues each time.  
1. eye discipline (sorry for the butch-ism).
2. assignments.
3. impatient.
4. talent / experience issues.
TD1:
Beasley should be assigned to the flats. This is his play to make. He creeps up on the line before snap and aggressively pursues the RB anticipating he will get the ball.  Pass goes to the sideline and now Beasley is way out of position.  Redmon or McMurray gets manhandled by the blocker.  Another blocker handles Turrentine (maybe?).  A pursuing LB, possibly Spillman, pushes Farooq out of the way and out of the play in pursuit.  The rest are out of the play with bad angles.  Hood runs stride for stride but never attempts a dive at the feet.  
TD2:  
Boo is put into coverage.  His receiver is 2nd from the outside and he is playing close to the line.  They two receivers are kind of bunched over there.  That placement on the field is very important.  He is way out there.  It is the short side of the field.  He was watching the play action pass the whole time.  He was flatfooted at the hike.  He was literally beaten on the first step from scrimmage.  He had no chance.  By the time he realized the RB was out of play, his assignment was already passing him by.  He is STAR so he has both pass coverage and run support but his team mate was covering the RB already.  He either is confused, undisciplined, doesn't trust his team mate, too hungry to make a highlight or some combination of factors.
TD3:  
A hot mess.  Basically had 8 in the box.  Redmon follows his assignment in motion.  At snap, we are playing heavy on the Right side.  Telander goes Ham towards the line as if run.  He 'handed off' the TE and no one took him.  We had 3 players standing around on the R side.  UK QB actually made the harder throw to Redmon's assignment in back of EZ.  The TE Telander handed off was wide open on the left side in the flat.  Nobody within 15 yards of that guy.
At this point in the season, I don't know how you "coach up" these deficiencies.  These players are not reading the same alignments by the O.  They aren't playing within their assignments. They are undisciplined, inexperienced, and talent deficient.  
I would like to see us be create some blitz packages for Boo, Perlotte and Spillman.  Boo is a liability in scheme but has the talent to be a "go do this play" kinda of guy.  Perlotte and Spillman because of the flashes of talent from them.  Telander honestly looks like a run defender but not an every down LB.
