The Pistons and Spurs are teams on a similar trajectory for this season, which is the bottom of the standings and the best shot at Victor Wenbanyama. However, how they have gotten there is completely different.
The Spurs started out the season 6-6, and have tanked hard over the last couple months. They were projected to be near the bottom of the standings before things got started, so their decent start was more of a fluke and what they are doing now is what was expected.
For the Pistons, they started out very bad, but have gradually improved.
