Maalik Wayns has signed a one-year contract with the Sixers.

“It’s going to be a great experience for me, I’m just so happy and excited that things worked out the way they did,” said Wayns, who went undrafted in June. “I was confident that I was going to catch on with somebody. I knew I was going to play in the NBA. I just didn’t know where.”

Wayns averaged 11.7 points, 5.7 assists, 2.3 rebounds during the Orlando Summer League.

“I thought I played well in Orlando and there were rumors going around that a team or two were looking to sign me,” said Wayns. “But nothing happened. Still I never lost confidence that things would work out. The Sixers talked to my agent (Andy Miller) and we got a contract. I was thinking the whole time of just going to training camp and trying to make a team, really without any security. This is an added bonus.”

C.J. Miles, according to a source, is drawing serious interest from the Lakers.

Miles, who has already met with the Mavericks and Cavaliers, could make a decision within the next 2-3 days.

The Lakers still have the $3 million mini mid-level exception available to sign an incoming free agent.

The Boston Celtics have signed Jamar Smith.

Smith, a 6’3” guard, appeared in 44 games last season for BK Prostov in the Czech Republic and averaged 14.8 points and 2.5 assists while shooting 39.3% from three-point territory during league games.

Smith also appeared in two games during EuroCup qualifications and in six games of the EuroChallenge. Smith played for the Celtics during the 2012 Orlando Summer League and averaged 9.2 points while shooting 45.0% from three. Smith was previously with the Celtics during training camp prior to the start of the 2010-11 season. Smith previously played for the Maine Red Claws of the NBA Development League. He played collegiately for the University of Illinois and the University of Southern Indiana.

The Celtics have signed Dionte Christmas.

Christmas, a 6’5” guard, appeared in 26 games during the 2011-12 season for AGO Rethymno Aegean in Greece and averaged 18.6 points, 4.4 rebounds, 3.0 assists and 1.6 steals per game. He shot 36.0% from three point territory and 46.3% from the field overall. He was an Honorable Mention All-American at Temple during his senior year (2008-09) and was named the Most Outstanding Player of the Atlantic 10 Tournament. Christmas played for the Celtics during their 2012 Summer League teams in Orlando and Las Vegas.

The Boston Celtics have signed free agent center Jason Collins. 

“Jason’s ability to defend in the post will be a great addition to this team,” said Danny Ainge.

Collins, a 7’0” center, averaged 1.3 points and 1.6 rebounds in 10.3 minutes per game last season with the Atlanta Hawks.

The Bulls officially signed Nate Robinson.

Last season with the Warriors, Robinson appeared in 51 games (nine starts) and averaged 11.2 ppg, 4.5 apg, 2.0 rpg, and 1.16 spg in 23.4 mpg. 

The Bulls are close to signing Nate Robinson to a one-year, veteran's minimum deal.

Robinson averaged 11.2 points on 42.4 percent shooting, 4.5 assists, and 1.2 steals in 23.5 minutes for the Warriors last season.

Dallas and Orlando had exploratory talks last week regarding Dwight Howard and "will probably talk again,'' Mavericks general manager Donnie Nelson confirmed.

Terms of a potential deal have not moved beyond the preliminary stage.

"There's just not much there,'' Nelson said.

One source indicated the Mavericks are holding out hope that Howard stays in Orlando through next season, or goes to Houston as a one-year rental.

Dallas could have enough cap space next summer to sign Howard to a max-level deal.

The Clippers have acquired Willie Green in a sign-and-trade agreement with the Hawks for Sofoklis Schortsanitis.

A nine-year NBA veteran, Green has averaged 9.1 points, 1.9 rebounds and 1.5 assists over his career.
