Denver took them to 7 and they held up pretty well but you are right Indy had the tougher road to this stage so they might be better mentally prepared.
I got OKC in 5. Watched this team all year, especially since I had SGA and JDub on my fantasy team. I just can’t see any team beating them when they are locked in.
And even then, "tougher" is marginal, if not subjective simply bc OKC put belt to ass
--Conference Finals Opponents
MIN: 6th in Defense / 10th in Offense
NYK: 12th in Defense / 5th in Offense
--- SemiFinals Opponents
CLE: 8th in Defense / 1st in Offense
DEN: 22nd in Defense / 4th in Offense
Do NYK or the injured/pussified version of CLE beat MIN or DEN (or LAC) in a series? Idk.
