Kevin Durant grabbed the majority of the headlines this summer with his blockbuster move from the Oklahoma City Thunder to the Golden State Warriors in free agency.
However, he wasn't the only other big name on the market to change things up.
Al Horford is a perennial double-double presence who had spent his entire nine-year career with the Atlanta Hawks. Given the Georgia-based franchise's status as a contender in recent years in the Eastern Conference, many assumed the forward would stay in the south.

The 30-year-old had other ideas. Horford signed a four-year, $113 million deal with the Boston Celtics this summer and the storied organisation looks better equipped than ever to make a serious run at the east.
In a Q&A with the Atlanta Journal-Constitution, Horford explained his logic behind the move.
"It was extremely difficult but at the end looking at the future of the team and having an opportunity to win in a different scenario for me," said Horford, a four-time All-Star. "It wasn't an easy decision for me but I think at the end Boston just felt it was the best fit for me when looking at everything from their players top to bottom, the amount of players they had and the potential there."
He's right; with Isaiah Thomas and Avery Bradley amongst others in the ranks, the Celtics were only really missing a frontcourt superstar.
Horford brings that to the table, and after his meeting with the Celtics, he knew he had to make the call.
"There was a lot of impact on me with Danny Ainge and coach (Brad) Stevens," Horford said. "It was a very positive meeting. Two of their owners were in the meeting and three or four of their players were there too.
"They seemed like a very close group and were focused on what their goal was and they got my attention. I wasn't sure in what direction I was going to go. But I knew in order to leave Atlanta it was going to take a very special situation."
After finishing fifth in the Eastern Conference last season, can the Celtics challenge for the top seed with Horford on board?
