With +.500 teams, we're currently: 1-1 vs Golden State 1-2 vs San Antonio 1-2 vs Memphis 1-1 vs Utah 2-1 vs OKC 0-1 vs Cleveland 1-1 vs Toronto 1-1 vs Boston 2-0 vs Washington 1-0 vs LA Clippers 0-2 vs Atlanta 0-1 vs Indiana That's an 11-13 record. Not good, but not terrible either.
There are only 5 teams with winning record against .500+ teams: Dubs, Spurs, Grizz, Cavs, and Celtics.
The Rockets won't be able to join that list for a while. They have one game against a +.500 team remaining this month and it's the final game in February(vs the Pacers). Of course, 5 of their next 6 after that are against +.500 teams. And the lone sub-.500 team is Chicago who are currently 25-26.
Yeah it's not the easiest feat. That's a list of very good teams. Memphis are so underrated by the league and media it's crazy.
