Horford agrees to deal with Celtics

The Al Horford era in Atlanta is over.

With it goes nine seasons of unprecedented success for the Hawks organization. Whether the run continues following several organization-altering moves over the past two days remains to be seen. If so, it will be done without the player who has been a cornerstone of the organization for nearly a decade.

Horford agreed to a maximum deal of four years, $113 million with the Celtics on Saturday. The Hawks failed to offer the four-time All-Star center a maximum deal of five years, $153 million. After imposing of Saturday evening to reach a deal, Horford will leave the team he joined as the No. 3 overall pick in the 2007 NBA Draft.
