   Why?  Right now there are damn few skin impressions of theropods that can
conclusively show anything.  Absence of evidence is not (necessarily)
evidence of absence.  Given that 1) Dromaeosaurs were very closely related
to Archaeopteryx and 2) Archaeopteryx had feathers it makes sense that all
maniraptorans had feathers.

   Then there's that ornithomimid skin impression that hints that it had
some sort of featherlike structure growing out of its skin.....
