Ken Berger of CBS Sports also detailed one other factor that went into Horford's decision and that wasn't just the signing of the oft-maligned Dwight Howard.

Factor No. 2: Atlanta's signing of Dwight Howard. Could there be a more contradicting force in the NBA to Horford than Howard, in terms of substance vs. style?
"He didn't want to play with Dwight," a person familiar with the situation told CBS Sports.

And you can't blame him considering how different their styles are and how differently Horford would be forced to play when the two were on the court together. And that's why you don't make moves until you sign your mega star first, folks.
