I agree that many times the reversed hallux is an artifact of  preservation. In 
this case (however) what I saw in the fossil made me doubt. It was  clear and 
articulated, and the 'curled' opposable fourth toe was longer than many I have
seen.  It was also clearly not a dromaeosaur, but that is already acknowledged.
I still have my doubts... have you seen the fossil itself?
