I know it may be a bit early for him, but he won't be here when I pick next, and he rounds out my starting 5 perfectly. Gives Minny a very very good defensive squad and a balanced scoring team.
PG:Jameer Nelson
SG: Tayshaun Prince
SF:Paul Pierce
PF: Rashard Lewis
C: Joakim Noah

My take: I love Rashard, but I like him best as a SF. Right now, in my eyes you still have three small forwards, and your PG is a guy who is better in a half-court offense, rather than a transition one.
I love your shooters, but I think a lineup built around shooters is very flawed without the dominant offensive big man (i.e., Howard, etc.) to build around. In Orlando, for instance, most teams double team Howard, leaving one of their great shooters open. In Minnesota, teams will be able to single cover all of your guys.
That said, kudos to you, because I'm judging your team as a flawed almost-contender, rather than as a bottom of the barrel lottery team. You've pulled off a heck of a turnaround.
