The Dallas Mavericks are plotting an aggressive push to acquire Carmelo Anthony, even if they don’t get assurances that the three-time All-Star would agree to a contract extension as part of the trade, league sources told CBSSports.com.

Despite his team’s emergence as one of the powers of the Western Conference -- and, as Dallas proved Monday night in Miami, the whole league -- owner Mark Cuban is said to be not only willing to take a chance on Anthony, but eager to steal him from the Nets, who are owned by his billionaire rival, Mikhail Prokhorov. In a deal that would provide Denver with little more than future savings, the Mavs are planning what one rival executive described as a “hard” push.

The Mavs’ interest has yet to take the form of a concrete offer, as one person connected to the Anthony drama told CBSSports.com Tuesday that Dallas had yet to present one. Any prospects the Mavs might have to pull off such a coup would be contingent on Anthony declining to sign an extension with New Jersey. With a signed extension as part of the deal, the Nets still possess by far the most attractive assets to Denver -- Derrick Favors, the expiring contract of Troy Murphy, and multiple first-round picks.

But that is the question that the Anthony saga has hinged on for months. Part of Dallas’ strategy, according to sources, is to shift the Anthony discussions to what Cuban recently called the “rent-a-player” phase, which would drive down the price and encourage other teams to present offers without assurances that Anthony would stay put for five years -- the two he has remaining (including the early-termination option for 2011-12) plus the extension.

Such potential suitors, including the Mavs, do not have enough of what Denver is looking for to compete with New Jersey’s best offer. But if Dallas is successful in shifting Denver’s focus to “rental” deals, the Nets would then have to decide how much they are willing to give up to acquire a franchise cornerstone for their move to Brooklyn -- even if Anthony could leave them in the dust as a free agent before the team even got there.

Meanwhile, the Nuggets remain in a patient posture and are not in any apparent rush to push a New Jersey trade to fruition. And after acquiring two more first-round picks in a three-team trade with the Lakers and Rockets last week, Nets executives are continuing their ongoing efforts to sweeten the deal for Anthony by acquiring a veteran he’d want to play with in Newark, N.J., for a year-and-a-half. Such inducements could come in the form of Al Harrington and/or Chauncey Billups, whom Anthony might be comfortable having on board. The other scenarios, according to one executive familiar with them, are numerous and “beyond challenging” because multiple teams would be needed.

Among the contending teams with the deep pockets and championship core to take a risk like trading for Anthony without a signed extension as part of the deal, Dallas has the most expiring money to make it worth the Nuggets’ while. Any Dallas proposal would have to include the expiring contracts of Caron Butler and DeShawn Stevenson. More money would need to be added -- Tyson Chandler? -- or a third team would need to be recruited in order to take Harrington and/or Billups off Denver’s hands.

The notion of Anthony going to a contender -- or to the Nets, for that matter -- without signing his three-year, $65 million extension is exactly what New York Knicks officials are hoping for. Sources say the Knicks continue to believe that the longer the Anthony situation plays out, the better their chances of landing him through a trade, or more likely, as a free agent after the season and anticipated lockout. New York has been Anthony’s preferred destination since his operatives began pushing for a trade in September, and a person directly involved in Anthony’s decision-making process told CBSSports.com earlier this month that he’d become more entrenched in his desire to agree to an extend-and-trade only if he would up with the Knicks. CBSSports.com also reported that Anthony has not shared his position with Nuggets officials, and that Nets officials have been told differently by Anthony’s camp.

Another team that various team executives believe is very much in the mix -- either to make a push to land Melo as a rental or become involved as a third-team facilitator -- is the Rockets. Houston fully expects to receive a disabled-player exception for Yao Ming totaling $5.8 million and already has a $6.3 million exception from the Trevor Ariza trade. Such exceptions can’t be combined, but individually they could be used to absorb a contract -- such as, for example, the Nuggets’ J.R. Smith’s or Harrington’s -- without sending equal money back. In return, the Rockets would either have to get a player they want or be compensated accordingly with draft picks or other assets. The Rockets also are flush with the expiring contracts of Shane Battier, Jared Jeffries, and even Yao, whose contract is insured due to his season-ending foot injury.

Rockets owner Leslie Alexander has a history of bold moves, and has placed few restrictions on his front office, led by GM Daryl Morey, to spend money in order to win. The Rockets, for example, are currently a tax-paying team and are under no mandate from ownership to shed salary even though they are off to a slow start and have lost Yao for the season -- and maybe for good.

A dark horse in all of this? The Mavs’ opponent Tuesday night, Orlando. The Magic have a little more than two months before the Feb. 24 trade deadline to see if their revamped roster will be good enough to contend for a title after this week’s blockbuster trades with Phoenix and Washington. But the only piece that is likely to be available and enticing to Denver is Jason Richardson, whose $14.4 million contract expires after the season. Richardson cannot be combined with other players in a trade for 60 days, which would leave just enough time before the trade deadline to involve him in the Anthony discussions.

If -- and this is a big if -- Anthony is still a Nugget by then.

I have MANY years of experience in trying to appreciate steaming piles of dogshit.

I am not a legal expert, how many times do I have to say it?

You might as well combine all the star players who will never win anything on the same team.

rpb is wrong. Phil McCracken is useful.

RPB is right. You suck.

How about getting Erick Dampier

Dirk especially has a similar game to Carmelo.

Yes but Dirk can't WAIT to have someone to defer to in pressure situations. He doesn't want to be that guy. He never did. That would immediately become Carmelo's team, with Dirk as a second option.
