THEME:   "Child's Play":  phrases ending in kinds of toys    
GOOD ONES:     Morsel mentioned in 80's…   SHRIMP-ON-THE-BARBIE [she's a doll]   
Turf controller   GANG [not edging or weed killer as I thought]   
Show places?   THIRDS [note two words, as in horse racing]   
Driving instructor   GOLF-PRO   
Grave offender?   GHOUL   
Neat finish?   NIK   
Bugs with weapons   MORAN [the gangster not the bunny or insects as I thought]      
BTW:   The title was only partially true as the upper right was tough:  CRACK (Figure out) and HOLES (Case weaknesses) crossed by TRURO      
Like drag strips   LOUD [only rarely; mostly they are silent]   
   
As a companion   ALONG [too far removed from what 
along means; it does not suggest companionship but rather accompaniment 
viz., riders on a train or guards with prisoners]      
Sunday morning quaterbacking:   
INNIE clued by "Navel concavity" might have been "Navel position" or "Navel type"   
BOLTS clued by "Nuts go-with" might have been "Not nuts"      
RATING:  
 
 
   Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
