* Insurance: Without Miller, the Thunder's second unit would be relying heavily on Jackson and Jeremy Lamb. While Jackson proved in the playoffs that he's ready for more responsibility, Lamb remains an unproven commodity. If he's ready, great. If he's not, Lamb could take a backseat for another season and Miller could fill the role of spot-up shooter. The postseason is really when Lamb's preparedness will be put to the test. If he's not quite ready for the moment, Miller's proven track record of playoff success would be a terrific fallback plan.
* Makeup: By all accounts Miller is a team-first player. He's been labeled a winner, a low-maintenance teammate and a guy who is willing to sacrifice for something greater than his individual desires. In other words, he's got the prototypical personality for the Thunder. It would help Miller fit in from Day One, as well as be an example to younger teammates. Few players have that ability or desire, which is one of the main reasons the Thunder has pursued Miller so aggressively.
