Hawks captain and All-Star Joe Johnson said he will not sign a contract extension with the Hawks and will play out the final year of his contract this season.
Johnson will be an unrestricted free agent next summer.
The Hawks extended a four-year, $60-plus million contract offer to Johnson this summer. But Johnson said he decided not to sign the extension after mulling it over during the offseason.

Can't say I blame him. I honestly think this might be in JJ's best interest as well as the team's. Might as well see how good we'll be as a team b4 committing and getting buyer's remorse.
I wonder if Woody's contract situation plays into this at all.
