No, the femora in _Cryptovolans_ are long enough (and preserved in such a 
position) that I doubt it.

But I'm not sure I see your point--a nonbird theropod could have an effective 
leg length just as long as a secretary bird without having such elongated 
lower limb elements, since the femur would contribute to the effective leg 
length, unlike in modern birds.
