The way Boston Celtics power forward Jared Sullinger tells it, he's now walking on even ground for the first time in almost two years.

Prior to February back surgery, he said Friday, his right leg "dragged" behind his left one, an issue that plagued him dating back to his days at Ohio State. The problem stemmed from his back issues, which caused a precipitous fall to No. 21 on draft night and ultimately led to season-ending surgery in February. Teams shied away from Sullinger due to fears about his body, but now he believes his back is fully healed.

"It's completely fixed, so you can run and tell that," he said while helping Sun Life Financial to improve and redesign the Victory Programs' Revision Family Home in Dorchester.

Still in the middle of a rehabilitation process designed to have him ready by training camp, the 21-year old isn't sure exactly how much will change about his game now that he's healthy.

"I don't know," Sullinger said. "I haven't fully did a max jump or anything, so I really couldn't tell you. It's going to be interesting to see. I'm just as dumb as you are at this point of knowing what my career will hold in the future."

After averaging 6.0 points and 5.9 rebounds during his injury-shortened rookie campaign, Sullinger has already changed at least one critic's opinion. During a recent interview with Celtics.com, strength and conditioning coach Bryan Doo said he initially doubted the power forward "as a person" after seeing him play at Ohio State. Not impressed by Sullinger's physique, Doo said he wondered how much the skilled big man worked on his "terrible body."

Though meeting Sullinger and seeing his work ethic in person completely changed Doo's feelings about the former Buckeye, he still jokes about the extra pounds Sullinger hasn't shed.

"He tells me that all the time. He always, every time I score, says, 'Look at that fat boy scoring. I don't know how he scores,'" Sullinger said with a laugh. "But finally we were around each other, and it's mutual respect. I can understand that, but B-Doo, that's my guy. I have no complaints with him."
