While the lengthy offer sheet negotiations for Clippers restricted free agent forward Lamar Odom continues, Heat coach Pat Riley proceeded to meet one of his offseason objectives of getting "longer" by adding two front-court players Friday.

The Heat signed its third forward in the past eight days by adding 6-foot-9 underachiever John Wallace, who after six years in the NBA was toiling in Greece last season.

Miami also signed 7-1 center Loren Woods, who despite playing just 98 career games in two seasons with the Timberwolves apparently made an impression in an exhibition game last summer, when he torched the Heat for 14 points (7 of 8 shooting) and seven rebounds in 23 minutes.

Both signed minimal one-year deals as the Heat continued to squirrel away cap money for the Odom sheet, which is believed to be in the $60 million range over six years.

The Woods' signing, as well as the recent addition of power forward/center Samaki Walker, may signal the end of backup center Vladimir Stepania's two-year stay. After playing for three teams in five seasons, the 7-1 Stepania, who is coming off his best season, is seeking the stability of a multi-year deal.

"First of all, I want security and have a chance to play good basketball on a good team," said Stepania, who has drawn interest from the Mavericks and Grizzlies. "I've had two good years and have enjoyed playing for Riley. I'm not closing the door here. They may come up with something."
