The shooting guard was named the NBA's sixth man of the year last season, having averaged 18.1 points per game from the bench.
The 28-year-old told ESPN: "I've always wanted to start. Everybody knows that. I won the Sixth Man [Award] last year, so I felt as though there's nothing left to prove at the sixth-man spot.
"But at the same time, if that's what my team needs me to do, that's what I'll do. If Coach wants me to be a sixth man, I'll be a sixth man. If he wants me to start, I'll start. That's up to him."
Smith will miss the first five games of the season while serving a suspension for violating the league's drug policy.
