The power forward position is the only spot in the starting lineup where legitimate debate is warranted.
Boris Diaw has been continuously increasing his stock since he joined the team, culminating with an incredible playoff performance.
On the other end, Tiago Splitter made a significant jump during the 2013-14 season, establishing himself as a viable defensive anchor and a capable offensive talent in the post.
Both Diaw and Splitter have their individual strengths and weaknesses, and each will be used heavily in the upcoming campaign.
As for which one will start, however, the scale tips in Splitter's favor. Namely, due to his role as Tim Duncan's natural successor, but also because his height and defense put him at a clear advantage against teams who play two post presences.
If, however, the opposition deploys a small-ball lineup, the case can be made for Diaw to start in Splitter's stead.
As he did throughout the previous season, Gregg Popovich will likely switch the two big men depending on the matchup. As for the "regular" starter, though, Splitter's upside defensively and Diaw's ability to lead the second unit make Splitter the obvious choice.
