Tell me which of the following things you disagree with:
1) The Warriors, Spurs, and Rockets have all been better than the Cavaliers in this regular season.
2) Kyrie, Love, and Thompson are a more talented supporting cast than Aldridge / Pau / Parker or Gordon / Ariza / Anderson.
3) James Harden has more offensive responsibility for the Rockets than LeBron has for the Cavs.
4) James Harden is playing closer to his maximum potential on a nightly basis than LeBron is for the Cavs.
5) James Harden and Kawhi Leonard are both more productive scorers than LeBron this season, and their scoring efficiency is about the same.
6) Stephen Curry is scoring more than LeBron and almost as much as Harden, and is the most efficient of this whole group.
7) Kawhi Leonard is playing the best defense of any of the plausible MVP candidates.
8 ) The Rockets are better than you expected them to be during this regular season; the Cavs are not as good as you expected them to be during this regular season.
From your response above I take it that your basic position on this is that the Cavs are really just not a very good team without LeBron, whereas the Rockets or Spurs might be at least competitive (and well coached) without Harden or Kawhi.
