If we are going to do "fantasy" lineups, I prefer to do ones that don't require lots of improbable steps to get there. That being said, the only assumption I'll make is that White goes to the Bobcats) here is mine:
C - Mark Blount (Lampe and Voskuhl as backups)
PF - Stoudemire (McDyess as backup on both positions)
SF - Marion (Carbakapa as backup)
SG - Johnson (Iguodala and Jacobsen as backups)
PG - Brent Barry (Barbosa as backup)
Eisley on IR
Blount and Barry are widely believed to be available at or just over the MLE. Assuming White goes and the cap is set at $45, this would give the Suns $17 million to play with:
Iguodala - $1.9
Blount - $5.5
Barry - $5.5
Dice - 2.5
-------------
Total - $15.4
It would leave $1.6 million for Vujanic if he is available. Of course, if the Suns drafted Iggy and signed Barry, they could probably be able to trade Jacobsen for another million in cap space.
This team has the potential to be an upper tier contender even if Lampe does not develop quickly. If Lampe turns out to be a stud center, this team would have the depth to go a long way.
