Who do you rank higher: Chad Dawson or Sergey Kovalev?

You have 2 former LHW champs who were rated highly in their prime before they both fell from grace, possibly due to Andre Ward. Both Chad Dawson and Kovalev were pretty hyped up back then, both have victories over an old Hopkins, and they had the tools to be great but they both didn’t have the mental toughness and focus to put everything together. As far as achievements goes at 175 who would you say ranks higher in your opinion? And who do you think fell from grace the worse?
