Source: Deron Williams working out at Nets facility

What does it mean that Deron Williams is said to be working out at the Brooklyn Nets' training facility this morning as he's supposedly weighing the massive decision to either re-sign with the Nets or agree to join his hometown Dallas Mavericks?

ESPN.com's Chris Broussard tweeted that a source tells him that Williams is indeed working out at the Nets' facility.

Is he saying good-bye to the few teammates remaining on the roster? Is he giving newest Net Joe Johnson a tour?

Would he really show up at the facility for a workout if he's on the verge of leaving for the Mavs?

The drama continues to unfold. A decision could come today. It could come Wednesday.

All we know is the Nets continue to try to pry Dwight Howard away from the Orlando Magic, a move that would surely solidify Williams' commitment to the franchise, if they haven't secured it already.

Stay tuned.
