With or without the core of Kevin Garnett and Paul Pierce -- two players who may not be in Boston when training camp opens -- the Celtics need size. Adams is a project; the consensus among executives is that he will spend most or all of next season in the D-League, where he can get used to the speed of an NBA-level game. But Adams oozes potential. At 7 feet, 254 pounds with a wingspan of 7-5 and enormous hands (9.5 inches long, 11 inches wide), Adams is a physical specimen with extraordinary athletic ability who showed nice range for a big man at the combine.
