With the Suns now having 3 wins and being the second place team in the group, any team looking to advance as the Western Conference wildcard must have at least 3 wins. This eliminates OKC, who have 2 losses.
Of course, they can still make the playoffs, so this is only a minor problem for OKC.
Losing on that Curry layup hurt them more than beating us up by 40 helped them.
