Hawks' video tribute to Horford garners boos, then standing O

The Philips Arena crowd is sending Al Hoford mixed signals.

After spending his first nine seasons with the Atlanta Hawks, the big man joined the Boston Celtics last summer in free agency.

In his first game in the ATL as a member of the visiting team Friday, Horford was met with some boos during player intros and when he touched the ball early on. Then, between the first two quarters, the team honored the 30-year-old with a video tribute.
