Former Kansas University basketball forward Wayne Simien, who averaged 17 points and seven rebounds a game for Miami Heat’s summer-league team, did so as an unsigned player.

Simien, Miami’s first-round draft pick, signed a standard document that guaranteed the Heat would pay him under terms of the league’s two-year guaranteed rookie contract (for about $1.6 million total; third year is option year) in case of injury. He is expected to sign in the coming days.

Simien’s prospects of extensive playing time have changed somewhat since draft day.

The Heat re-signed forward Udonis Haslem and via trade acquired forwards Antoine Walker and James Posey.

“That trade eats up a lot of minutes,” said an NBA source, who did not wish to be identified. “Without Antoine, you had to figure Wayne would get a lot more minutes.

“One of the big questions now is whether (Alonzo) Mourning comes back. The bottom line is, Wayne’s minutes will probably be limited this year. We’ll have to see how it plays out. One advantage for Wayne is, aside from Shaq (O’Neal), he is the second-best post player on the team. Haslem and Walker like to float outside. He’ll still get some good time, maybe a lot of minutes depending on injuries and his progress. I know he impressed the Heat this summer.”

Simien currently is working out at the Heat’s summer-league facility in Florida. Next week, he’ll travel to New York for an NBA photo shoot for selected rookies.

The trade that shipped former Jayhawk Greg Ostertag from Sacramento to Memphis then over to Utah is one of the most complicated in NBA history.

For the record, here are the details of the five team trade: Utah gave up Curtis Borchardt, Raul Lopez and Kirk Snyder in exchange for Ostertag.

Memphis surrendered Ostertag, Jason Williams, James Posey and Andre Emmett for Eddie Jones and Raul Lopez.

New Orleans surrendered the draft rights to Roberto Duenas for Snyder and Rasual Butler.

Miami gave up Jones, Butler, Qyntel Woods, two second-round draft picks and the draft rights to Albert Miralles for Williams, Posey, Emmett, Antoine Walker and the draft rights to Duenas.

Boston surrendered Walker in exchange for Borchardt, Woods, two second-round draft picks from Miami and draft rights to Miralles.

Originally drafted by the Jazz in the 1995 NBA Draft (28th overall selection), Ostertag has played in 696 career games and averaged 4.8 points, 5.6 rebounds and 1.7 blocks in 20.0 minutes per game. He has played in 89 playoff games and averaged 4.2 points in 19.9 minutes per game.

“I missed playing for coach (Jerry) Sloan,” Ostertag said of the Jazz coach for whom he played 10 years. “I know what Utah expects in the locker room, what they expect in games and at practice. If we can get on the same page, play hard and follow what Jerry and the coaching staff are putting out there for us, then we will be compete every night.”
