ESPN NBA Rankings: Are Spurs Deserving of the Top Spot?

The ESPN NBA Power Rankings were released this week and the San Antonio Spurs were placed at the top of the list, do they deserve it?
The Spurs are fresh off of winning their fifth NBA title in franchise history, beating the back to back champs in the Miami Heat. With the Cleveland Cavaliers and Chicago Bulls having huge off seasons, there is no surprise in either being placed right behind them at two and three respectfully.
The Spurs have heavy competition in a loaded Western Conference as they have teams like the Los Angeles Clippers, Oklahoma City Thunder, and Portland Trail Blazers to worry about. The Bulls and Cavaliers however are likely to face each other if all goes as well, unless Charlotte or Washington take the next step. Toronto and Atlanta also look like solid teams, but it is unlikely that they contend this upcoming season.
The Spurs have everyone returning that played a pivotal role in their title run last season. Patty Mills and Manu Ginobili have some injury issues but should be fine. Kawhi Leonard might take the next step in his game and the Spurs added rookie Kyle Anderson, who might not have an immediate role as the Spurs are a deep team, but who knows?
Overall, the Spurs did win the title last season, coming out of the stronger conference, which makes them the top team, but teams like the Bulls, Cavaliers, Clippers, and Thunder are in the mix as well.
