Adrien's official height of 6 feet 6 1/2 inches with shoes is being held against him, but he also owns an impressive 7-2 wingspan and an 8-11 standing reach.

``They always talk about other guys being long,'' Adrien said. ``But you don't grab rebounds with your head, you grab them with your hands. I'm always doing that. I'm bigger than my height.

``I've gotten tired of it, but it's something that has been with me my whole life. People should forget about that.

``Basketball is a sport. I play Basketball. Size don't matter. Charles Barkley is a Hall of Famer, but no one ever talked about his height. I got the job done in college. If I was 6-6 and my wingspan was 6-6, then you could talk about it.''

Having to prove himself is nothing new. Celtics assistant executive of Basketball operations Leo Papile, who coached Adrien with the Boston Amateur Basketball Club, said he was recruited primarily by small Division 1 schools before UConn coach Jim Calhoun became impressed with him and offered a scholarship.

Adrien quickly found his way into the playing rotation with his toughness and ability to play much bigger and stronger than his height. He hopes he can follow in the footsteps of other undersized NBA big men such as Boston's Glen Davis and Leon Powe, ex-Boston College star Craig Smith of the Timberwolves, Houston's Chuck Hayes, and Utah's Paul Millsap.

Adrien worked out for Sacramento Friday, and has worked out for Houston, Miami, and Indiana. He took part in the recent Chicago predraft camp and has 4-5 more workouts on the horizon, according to his adviser, Will Dickerson.

``It's going to depend on his workouts as far as what happens to him,'' said an Eastern Conference general manager. ``He's not one of the top prospects, obviously. But he has a chance.''

Although Adrien doesn't have a workout scheduled with Boston, he said he would love the opportunity to aid the Celtics . A spot could open in Boston since Davis and Powe are free agents. The Celtics have the 57th overall pick, in the second round.

``Just give me a chance and good things will happen,'' said Adrien, who can be followed daily on Twitter at adrien4.

Said Papile, ``Jeff is one of my soldiers. I told him that a truly undersized forward at 6-6 is what you are. But he has extraordinary length for his size with a 7-2 wingspan and 8-11 standing reach. He plays bigger than 6-6.''

Between team workouts, Adrien has been working out in Los Angeles with the likes of projected No. 1 pick Blake Griffin and Hornets center Hilton Armstrong, a former UConn star. Adrien said that Griffin, another big man whose size is questioned, lives up to all the hype.

``Blake is the No. 1 pick and definitely well-deserving,'' Adrien said. ``I hear people saying that his arms are short. But this guy plays Basketball and grabs 14 rebounds with those arms. We go at it every day. It has made me better and helped me in my workouts.''
