Absolutely. It already has an asterisk. The first thing anyone says when this is brought up is Love and Irving not playing.
No finals team in my memory has ever lost their 2nd and 3rd best player. Probably did happen long ago but definitely not in the 2000-2016 seasons.
To further the OPs point, there is no way people would not be saying "When both teams were healthy the Cavs won". It would literally be the first thing every nba writer will put out the day after if the Cavs did beat GSW in a rematch.
