The Hawks (27-22) have stumbled since a 20-10 start, and personnel changes may be coming as speculation swirls around Josh Smith.

The forward, averaging 16.9 points and 8.5 rebounds, will be a free agent after the season and could be dealt before the trade deadline.

Smith had 19 points against New Orleans on Friday, but the Hawks fell victim to Greivis Vasquez's triple-double in a 111-100 home loss.

The Hawks have allowed opponents to shoot 41.6 percent on 3s as they've lost four of six, and teams are hitting 38.3 percent from 3-point range against Atlanta this season -- among the highest marks in the NBA.

The Hawks led the Hornets by 14 in the second quarter but were outscored 29-16 in the third.

Meanwhile, the Mavericks (22-28) are starting to look better at it, having gotten off to a 2-0 start on their five-game homestand after a 3-5 stretch. Dallas has won six of eight at home, while Atlanta is 1-8 in its last nine on the road.

Shawn Marion scored 26 points -- 14.4 above his average -- in a 116-91 win over Golden State on Saturday. Marion has averaged 17.7 points and 56.0 percent shooting in his last seven contests.

The Mavericks had won three in a row over Atlanta before a 106-89 loss in the teams' regular-season finale April 26. Smith had 23 points and shot 10 of 14 to go with nine rebounds and seven assists.
