THEME:   none, but 28 blocks   
GOOD ONES:     Place for an old school tie?   ETONCOLLAR [is the school or tie old?]   
Hit home?   SIDEA [I thought baseball: slide or score]   
Goes downhill fast   SKIS [oldie but goodie]   
One to horse around with?   Stablemate   
Tip for a writer?   NIB      
BTW:   Given that we are no longer told if an answer is more than one word, is it necessary to use question marks after tricky clues?  Looking at the four good ones above, I'm not so sure.       
Bureau where stats abound   SPORTSDESK [hardly a bureau]      
EINES is German; 
NENES is Portuguese; and neither is used in English, ever --- unless NENES refers to geese.      
Can't believe I remember Toni Basil or know who Heidi Klum is.  I'm stumped about the former and glad about the latter --- she is absolutely charming.      
Sorry about the spam which the site management seems to tolerate better than I.RATING:
