In yet another setback, Agent Zero had surgery this morning on the same knee that's been bothering him the past two seasons. He is expected to be out until December, but after three surgeries it's a little bit difficult to put too much stock in that timetable. This is not the most encouraging news for Arenas fans, but it's nice to know well ahead of draft time. If you were thinking of drafting him early on, think again. This is good news, however, for folks who manage to land Caron Butler or Antawn Jamison in this year's drafts.
