The Hubble Law long predates any dream of dark energy. It also does 
not automatically imply a "big bang". Hoyle's old "steady state model 
takes it into account
It was discovered by Hubble and only implies that the universe is expanding.

Hoyle's steady state theory is based upon continuous creation of 
matter everywhere in the universe. It only fell out of favour after 
George Gamow and colleagues' prediction that a "big bang" theory 
implies a CMBR at 5 degrees was confirmed (actual value just under 3 
degrees absolute).
