losing Josh Smith would be much more of a blow to their playoff hopes than losing Lou Williams.
They are a team in disarray, not happy with JSmoove since they suspended him. This is hurting their playoff hopes as much, if not more as Lou Williams being out.
Consequently, I agree that losing Williams may give them some impetus to get a guard (Lee could start for them next to Teague)and if Smith isn't happy in Atlanta, and Atlanta isn't happy with him they will need a PF to replace him (Jeff Green) or two (Sullinger), and Green can also play the 3.
Not saying it's gonna happen, just saying that with Smith's situation and its obvious very negative effect on the team and with Wms out, I can easily see Ferry trying a 1 for 3 to fill his roster.
