Al Horford was by far the biggest man in the gym this past weekend as he towered over the 120 or so kids at his basketball camp at Emory University.

But when Horford returns to the court to play center for the Hawks, he's considered undersized for his position. For the second consecutive offseason, an emerging storyline is if the Hawks will add a full-time center so Horford can permanently slide to his preferred power forward position.

But the bigger question might be if Horford will figure larger in Atlanta's offense in 2011-12. Horford was by far the team's most efficient scorer last season but ranked just fourth in field-goal attempts per game.

"It will be interesting because I've always been very team-oriented," Horford said at his camp. "If coach [Larry Drew] comes and tells me, 'Listen, I want you to develop more [in isolation] and I want you to create plays,' I could adjust my game to that."

For years the Hawks have been a guard-oriented team with Joe Johnson as the anchor. Johnson had his worst season in Atlanta last season and his deliberate style sometimes bogged down Drew's motion offense.

The limitations of that approach became clear during Atlanta's Eastern Conference semifinals loss to the Bulls. With the exception of two games, Atlanta's offense was disjointed against a superior defensive opponent and the Hawks lost the best-of-seven series in six games.
