Former Timberwolves first round selection, high schooler Ndudi Ebi, Northwestern's Jose Juan Barea, Memphis point guard Darius Washington and swingman Pat Carroll are fighting for the final Mavericks roster spot.

"What you have are four young guys with upside who are worth investing in," president of basketball operations Donnie Nelson said.

Ebi, a 6-9 forward who played at Houston Westbury Christian, jumped to the NBA from high school. He was taken 26th by Minnesota in 2003, three spots ahead of Josh Howard.

But he played just 19 games in two seasons before being released in November. Ebi spent last season with Fort Worth in the National Developmental League and attended Hakeem Olajuwon's big man camp in Houston this week.
