Did the Mavs know something early Saturday?

How excited is Dallas Mavericks owner Mark Cuban to begin the season and hoist his first championship banner over the American Airlines Center?

Reports from media members who were at the AAC early Saturday morning after the Dallas Stars-Toronto Maple Leafs hockey game earlier in the evening have been firing some interesting tweets throughout the evening.

The lockout was settled at about 2 a.m. CST. But James Mirtle, a hockey writer for the Toronto Globe Mail, tweeted that workmen were starting to put down the facility’s basketball floor .

And David Alter, a reporter for the Fan radio station in Toronto, evenof the floor in place before the settlement was announced.

Considering the championship, should we be surprised about Cuban’s enthusiasm?

Let the games begin, thankfully.

Spurs slowly getting business in order

The Spurs unlocked the doors to their practice complex Thursday morning, but players didn’t exactly barge through.

Maybe they knew members of the team’s medical staff were waiting inside, ready to give each player the requisite preseason physical exam.

Who likes an ice-cold stethoscope pressed against bare skin anyway?

Only three Spurs showed up for physicals Thursday: team captain Tim Duncan, second-year guard James Anderson and first-round draft pick Cory Joseph.

Most other members of the team aren’t expected to arrive until the weekend, and authorized offseason workouts won’t begin for another day or two.

According to one eyewitness, Duncan looked fit and trim.

All-Star point guard Tony Parker is scheduled to take a flight from Paris today and is expected at the practice facility Saturday or Sunday.

All-Star guard Manu Ginobili — who had been in San Antonio for a few weeks before the Nov. 10 breakdown in labor negotiations — will be in town Wednesday, according to his agent, Herb Rudoy.

Spurs general manager R.C. Buford and his staff continued talking to representatives of free agents so the club can be prepared for the opening of free agency, scheduled for Dec. 9.

A report in the Argentine sports publication Ole! on Thursday quoted former Spurs center Fabricio Oberto expressing hope that he might return to the Spurs for one more season.

According to that report, the Spurs had talked with Oberto’s Argentina-based agent before the lockout and showed interest in bringing the 36-year-old center back to the team.

Buford would neither confirm nor deny the team’s interest in the big man.

Traded by the Spurs in the 2008 deal that acquired forward Richard Jefferson, Oberto retired from the Portland Trail Blazers last season after suffering a recurrence of atrial fibrillation, an irregular heartbeat that twice sidelined him during his four seasons with the Spurs.

Cleared in July to play for Argentina in the FIBA Americas Olympic qualifying tournament in Mar del Plata, Argentina, Oberto was a solid contributor to his national team winning the gold medal in that grueling tournament. He is expected to play for Argentina during the 2012 Olympic Games in London.

Meanwhile, a significant hurdle on the path to a new collective bargaining agreement has been cleared. The players union will be reconstituted after receiving recertification cards from more than 260 player members. This will allow bargaining to continue with the NBA in an effort to complete a collective bargaining agreement in time for the planned Christmas Day opening of the 2011-12 season.

Jefferson’s tenure with Spurs looks to be over

Richard Jefferson arrived from Milwaukee in the summer of 2009, amid so much hope and promise, bringing with him the belief that he would be the missing piece to the Spurs’ latest championship puzzle.

After two mostly disappointing seasons as the Spurs’ starting small forward, it appears Jefferson will not be around for a third.

According to an source with knowledge of the Spurs’ plans, the team will exercise its one-time amnesty clause to waive Jefferson and free itself from the three years and $30.5 million left on his contract.

The move would nudge the Spurs’ payroll below the luxury-tax threshold and allow them full use of the $5 million mid-level exception in pursuit of a new starting small forward.

Jefferson’s replacement, in fact, might already have been present at Spurs headquarters Wednesday afternoon.

In a development perhaps tied to the decision to dismiss Jefferson, free agent was in San Antonio for a sit-down with general manager and coach that his agent, , said “went flawlessly.”

“The meeting went great,” Butler said Wednesday while waiting to board a flight at . “I enjoyed it.”

Though Butler has already visited the and still plans to sit down with the — two teams under the salary cap who could offer more than the mid-level exception — the Spurs have emerged as a strong contender to land him.

“Absolutely,” Brothers said. “He’s not wasting his time. He wasn’t in San Antonio to be nice.”

Butler has also met with representatives from the , who can offer only the $5 million mid-level exception as well. The Spurs also are considering Washington’s , who visited Tuesday, among other candidates to fill their impending void at the three spot.

The 31-year-old Howard, who in February 2010 was traded from Dallas to the Wizards for Butler, left San Antonio with a positive view of the Spurs’ operation. Like Butler, Howard is also weighing New Jersey and Chicago, and could still return to the Wizards.

“I know San Antonio is an , as far as everything they do,” Howard told the Washington Post on Wednesday. “It’s kind of like a mirror image of Dallas or vice versa. I know everything down there is cool.”

Butler, 6-foot-7, has averaged 16.6 points in nine seasons but had his 2010-11 campaign in Dallas cut short by a torn right patella tendon suffered on New Year’s Day.

With the Mavericks disinclined to offer more than a one-year deal, the 31-year-old Butler is not considering a return to Dallas. One factor that might lure Butler to San Antonio is a chance to play for Popovich, a coach he holds in high esteem, Brothers said.

The agent said Butler’s rebuilt knee passed a physical exam during his visit with the Clippers earlier this week, and he will be cleared for full participation in training camp once he signs with a team.

“We’ve got one stop left (New Jersey),” Brothers said. “Then it will be time to make a decision.”

With Jefferson, the Spurs seem to have already made theirs, although they can’t formalize his departure until the new collective bargaining agreement is ratified. A source with knowledge of the Spurs’ thinking says team decision-makers are waiting to double-check the exact language in the amnesty clause before making a final call.

Jefferson’s agent, , declined comment Wednesday.

For Jefferson, who signed a four-year, $39 million deal before last season and is scheduled to make a pro-rated $9.2 million in the shortened season to come, amnesty will mark an inglorious end to a tumultuous Spurs tenure. Yet it also offers the prospect of a much-needed fresh start.

Jefferson, 31, was a good soldier and a well-liked member of the Spurs’ locker room but a poor fit on the court. He averaged 11.6 points in two seasons and in 2010-11 shot a career-best 44 percent from 3-point range, but his uptempo strengths never quite meshed with the Spurs’ style.

Once waived, Jefferson — who signed a four-year, $39 million deal before last season and is due a pro-rated $9.2 million for the shortened season to come — will still be paid every cent he’s owed. His salary just won’t count against the Spurs’ payroll for tax and salary-cap purposes.

After amnesty, under the new CBA Jefferson’s rights will be auctioned off to the highest bidder, with teams under the salary cap given first crack. If a team claims Jefferson off waivers, the value of his new contract would be deducted from the amount the Spurs still owe him.
