Al Horford’s question came with a laugh and a smile as he walked down the sideline of the west court in the 76ers’ practice facility Wednesday afternoon.

“What are you doing here?” he said. “We don’t play for two weeks.”

After the handshake and taking a seat, it was time for the real question.

What are you doing here?

“I’m here looking for that championship,” said a still-grinning Horford, who cut off talks with the Celtics in June and bolted for more money and what he believes is a better basketball situation with Philadelphia. “Looking for that championship.”

Contract aside — and that was not an insignificant consideration — if anything should sting back in Boston it’s that Al Horford looked at the Sixers and the Celtics on his hoop GPS and calculated the former were closer to a title.
