Mirage and Caesars definitely should. Bellagio is a maybe. IMPERIAL PALACE definitely will have it. They are the king of futures bets. Most of the sunset properties should have it as well. Can't guarantee any of the above, but i imagine they should. The one place that almost 100% will have it is imperial because they deal heavily in futures.
As for your bet itself, good luck with it, the number you get should be good, but personally, I don't see anyone but Carmelo or Lebron getting it barring injury because of the already made public perception.
Good luck in all your plays.
