Bucks general manager John Hammond said he will try to shore up at point guard and center, finding some key backup help for Brandon Jennings and Andrew Bogut.
"We need to shoot it better," Hammond said of improving the Bucks' league-worst field goal percentage (43%). "There's hardly a team in the NBA that has enough bigs. A backup big would help.
"And the backup point guard spot - Keyon Dooling did a great job defensively, and Earl Boykins gave us some unexpected help at times during the season. But it's something we'd like to improve on.
"Maybe Keyon can come back and be better than he was this past year."
Dooling, who was used at shooting guard and point guard, will be in the second year of a two-year, $4 million contract next season.
