Honestly I don't even see that as a possibility unless one of Curry or KD is unable to play for whatever reason. The Warriors are just way too talented and deep to keep up with.
However, I do think that the Sixers will make the Eastern Conference Finals, and Vegas agrees for the time being.
LeBron vs. Simmons/Embiid would make me a fortune if I decided to sell my tickets. A seat at the top of the upper deck went for ~$200 for the regular season version of LeBron last week.
The energy in the arena is absolutely outrageous right now (I attended last night), and the fans are vicious to the refs consistently. The last game of the season against the Bucks, I sat 3rd row in the lowers right behind the Milwaukee bench. There was a guy in the seats just behind the basket, and he was heckling Jason Terry and the rest of the Bucks players mercilessly for the entire duration of the blowout without any consequence or care from the arena staff. Terry did snap back multiple times too.
