This is the sort of thing that makes NBA preseason worth watching: Position battles, even on bad teams:

The Phoenix Suns are a little more than a week away from their 2012-13 season opener against the Portland Trailblazers.

First-year head coach Jeff Hornacek is still tinkering with his roster and player rotations, but says there’s a pretty good position battle brewing.

“Probably the three spot, I’d say,” Hornacek told Doug and Wolf on Arizona Sports 620 Tuesday. “Marcus (Morris), P.J. (Tucker) and Gerald Green all lend different things.

“Obviously, P.J. is great defensively, he’s a guy that gets physical with other teams and really pulls up the defensive energy on our team. Then you have Gerald Green, who can really light it up offensively — I think we saw that in the San Antonio preseason game. And then Marcus is kind of a combination of both guys, he can score some, he’s working on his defense at the three spot.”

Whichever player gets to start may or may not actually play big minutes. Time could be split up pretty evenly. In which case, starting isn’t a big deal.
