The series will probably go 7 games (ratings and revenue are what the "Association" values most) and the outcome will be dependent on the what happens in the West.
If GSW beats Houston, the "upstart" C's will get the "nod". With KI and Hayward out, which will get major air play, the story line of the up and coming stars like JB, Tatum, Rozier will be the "hook" to get people to watch the series. No one wants to watch Lebron and the Cavs play GSW 5 years in a row and see the Cavs get trounced for the 4th out of 5th time.
If Houston wins, maybe the Cavs will be "allowed" to advance but that's by no means certain if the C's rising new stars look like they're ready to make it a competitive series with the Rockets. Also, there's the revenge factor. Harden v. Smart and they'll have re-plays on hand at every commercial break to hype the series of the game where Smart drew Harden into 2 silly offensive fouls.
