Could double M have been one of the greatest LHW's ever, had he stayed at 175?

He was a killer at LHW & judging by his relative success at HW, I really think he could have been.

I never thought the heavyweight division suited him as he looked podgy, but at light heavy, he was a monster, with a jab from hell, who massacred opponents.

Could Moorer have lived with the likes of Foster, Moore, Charles or Spinks at LHW or even bettered them?
