It was a huge risk at the time: Allen had come off double ankle surgery, at age 31. The player the Celtics were purported to be leaning toward in the draft -- Yi Jianlian -- was a highly coveted mystery. It wasn't a no-brainer, like the Kevin Garnett-Al Jefferson deal.Ray has been utterly healthy since coming to Boston, though -- he's played in 94 percent of the Celtics' games in the 2-1/2 seasons, just two games fewer than ironman Paul Pierce and a full 35 games more than the younger Garnett. And he's been good, too, a key component of the 2008 title run and a stunningly efficient weapon in 2009.
