Instead of using capspace on smith later, why not trade Rondo for Smith + Teague or Smith + a pick, and use capspace on D Will or KG+Others (if it's for Teauge:
DWill (max)
Bradley
?? #21/#22/Pietrus
Smith (I think he's most effective at the 4,
Gasol (and Gasol most effective at 5)
Johnson
#21/#22
Stiemsma
Moore
Vets
-Future ATL pick
or
DWill (max)
Bradley
?? #21/#22/Pietrus
Smith
Gasol
Teague
#21/#222
Stiemsma
Johnson
Vets
NO future ATL Pick
OR
Teague
Bradley
??
Smith
Gasol
#21/#22
Johnson
Stiemsma
Rest of capspace
In this scenario you'd go into it with Teague at PG (risky) but you'd have 20 million or so in space to re-sign KG, an SF (Green, Beasley) or another point (andre miller?)
