The Hawks are among several teams expressing interest in Rockets center Clint Capela, according to sources. Houston has received several calls on Capela, but is said to be unlikely to move him barring an overwhelming offer. Conversely, several teams are monitoring Hawks big man John Collins and feeling out Atlanta’s asking price, sources said. Collins has so far been part of the Hawks’ young core along with All-Star guard Trae Young. But the Hawks’ need for a more natural center is known, and they have expressed interest in Capela, Sacramento’s Dewayne Dedmon and Oklahoma City’s Steven Adams, too.
