What can i do with the memphis grizzlies

I've decided to do a memphis grizzlie dynasty because even though they're not good, i think their starting lineup is just about complete with great young talent. Casol, Randolph, Gay, Mayo and Conley. But what can i do with this team? What i mean is, how can i help them win an nba championship in 3 years? In this years rookie draft i'm thinking a small forward in the first round, and a 7 foot center in the second. I may make a trade or two to try to get another small forward just in case i can't resign Rudy Gay. So my question is, what do i have to add to this team to bring them an nba title in three years?

Hire three assistant coaches, so you can improve your players

Maybe you can trade some palyers in your bench for a strongner players...
