Strengths
Golden State Warriors - Talent and depth
The Warriors have such a large margin for error because of the level of talent they have at their disposal on the roster. Not to mention how deep they have gotten with their offseason signings like - Nick Young and Omri Casspi. The wing shooters only add to the already strong bench that Golden State had. They've been able to escape games with wins because their superstars were able to rest and then come up big in end-of-game situations.
San Antonio Spurs - Discipline and depth
San Antonio has always been known as a franchise to have a very effective, efficient and productive bench. But that's largely in part due to the system the team plays with rather than the talent of any given player on the team. Each player is able to contribute positively because he knows his role and plays that to perfection in the system. With their superstar Kawhi Leonard out, they'll need every player to play their role perfectly and beat the Warriors as a team.
