How so, all small coelurosaurs with "feather" impressions are maniraptoran 
(with the possible exception of _Sinosauropteryx_ who is apparently a mess). We 
have no coelurosaur impressions from non-maniraptorans that aren't multitonne.

Of the tyrannosaurs we see they did have scales. They might have been fine 
scales, but that doesn't mean that they were interspersed with hairs. Geckos 
have fine scales as well, sometimes to the point of feeling velvety, yet they 
show no hairs inbetween them. 

I honestly don't see how any known tyrannosaurid impressions are consistant 
with a elephantine view (they weren't naked, afterall).
