We're at the midway point of the NBA season, so let's take a look at how teams are doing. The clear runaway squads are the Cleveland Cavaliers (35-6) and Oklahoma City Thunder (35-7), who both have a 6 1/2-game lead over the second-place teams in their respective conferences.

The Oklahoma City Thunder regain the top spot in The Arizona Republic's recent NBA power rankings after defeating the previous No. 1, Cleveland.

It’ll be interesting to see which identity is able to better sustain success once the postseason is here. Throw in the possibility of a rematch in the NBA Finals, and how either team adjusts away from its identity could be the difference between winning it all or being disappointed by season’s end.
