Are you serious?? You must know about the 'fuzzy' theropods like 
Sinornithisaurus, Bepaisoaurus, Sinosauropteryx which  show a cobvering of 
hair-like structures. Feathers evolved from this- true feathers I mean like 
you see  in Caudipteryx and birds.

You compare apples & oranges !!!

So far, however, this hasn't happened.

See above -  there are small 'fuzzy' theropods


So, if we have a population of small therapod

Who cares???   Did you read my last messsage>?    It is not compulsary for  
ALL lineages to copy each other!@!!Why did creodonts return to the sea and 
evolve into whales, but why not dogs? They are both terestriall carnivores? 
That logic you use is nonsense!!!
