But, will he be on the roster when training camp opens?

Unless the Dallas Mavericks work DeShawn Stevenson into a trade scenario, he'll be an expensive piece at the end of the bench.

Agent Mark Bartelstein confirmed Monday that Stevenson made the only smart choice he really had by exercising his player to option to return to the Mavs next season for $4.15 million. Had the 10-year veteran opted out of the final year of his contract, he would never command that sum. Stevenson ended last season averaging 2.1 points a game, his lowest output since his rookie season with Utah. Just two seasons ago, Stevenson was averaging 11.2 points and logging more than 30 minutes a game with Washington.

The Mavs acquired Stevenson with Caron Butler and Brendan Haywood in the big All-Star break trade with the Wizards for Josh Howard and others.

There is the possibility that Stevenson could be the lone survivor of that deal. Haywood is an unrestricted free agent and can sign elsewhere, plus the Mavs aren't as enamored with the big man as they might have been upon his arrival. Butler, who is entering the final year of his contract, is a potential sign-and-trade piece.

Of course, there could be no survivors. Stevenson's deal adds him to the Mavs' list of attractive expiring contracts that could be used in a deal around the June 24 draft or after the free agency period begins.

Here's a look at the players, who at this point are contractually guaranteed -- or practically so (of course, anything can happen) -- of being on the roster when training camp opens:

G Jason Kidd (signed for two more seasons)
G J.J. Barea (Mavs expected to exercise team option)
G Jason Terry (signed for two more seasons)
G Roddy Beaubois (billed as team's future, but possible sign-and-trade piece)
G Matt Carroll (signed for three more seasons)
G DeShawn Stevenson (exercised player option for next season)
F Shawn Marion (signed for four more seasons)
