Jarrett Culver is the Minnesota Timberwolves' best option at starting point guard not because of his skill, but because of how he complements the already established pieces.
The Jeff Teague experience in Minnesota has had a similar arc as the Fantastic Four movie franchise: at first, it seemed like a great idea that had a lot of future potential backed by past success. However, due to sloppy writing, poor performances, and bad editing, each sequel became more painful to watch.
When looking at individual skill-sets, Teague is a more talented basketball player than Jarrett Culver.
