On this day: Braves, Celtics swap franchises; Al Horford signs

On this day in 1978, the Boston Celtics swapped franchises with the Buffalo Braves (yes, really!), and Al Horford signed with the team in 2016.

It is also the date former Boston big man Al Horford signed with the team in 2016. A product of the University of Florida, where the Dominican center won two national titles, Horford would be drafted third overall by the Atlanta Hawks, with whom he spent nine seasons.

The former Gator left Atlanta in free agency after the Hawks were swept by the Cleveland Cavaliers in the playoffs two years in a row, signing a four-year, $113 million contract with Boston.
