With roughly a month remaining before the start of training camp, the Sonics are still waiting to find out if restricted free agents Predrag Drobnjak and Reggie Evans will accept their qualifying offers or sign with other teams.

Both players were tendered one-year offers. During negotiations with Evans' agent, Dan Fagen, the Sonics increased their offer to Evans with a multiyear deal that would pay more than his qualifying offer (valued at slightly more than $700,000).

"We still haven't heard anything," Sonics general manager Rick Sund said.

According to league sources, Evans has received little attention on the free-agent market. As a rookie last season, the 6-foot-8 power forward led the Sonics with 6.6 rebounds per game, but he struggled offensively and averaged 3.2 points.

Drobnjak has drawn interest from Denver, and Portland has reportedly shown a desire to sign the 6-11 center who started 69 games and averaged 9.4 points and 3.9 rebounds.

If he signs his qualifying offer, valued at slightly less than $800,000, the Sonics would have four centers on the roster, including Jerome James, Calvin Booth and Vitaly Potapenko.

Seattle is entertaining sign-and-trade offers for Drobnjak.
