I know it's probably unlikely and would be difficult to pull off, but I kinda want us to sign Allen Iverson. Based on his interviews today he clearly still wants to play and I think he'd be a great 2nd string PG, and would keep the pressure on whoever ends up being our 1st string to keep playing well. It doesn't address our 3-point shooting problems since he only shoots a little over 30% but it would give us a pretty good scoring option with the second unit.
In an ideal world we pick up a 3-point shooting shooting guard and start them with Harris, Millsap, Favors, and Big Al and have a 2nd unit of Iverson, Hayward, Carroll/whoever we draft, Kanter/Evans, and some big guy (I would love to get Fes back). That bench would have more energy than any bench I can think of. It'll be fun to see what happens this offseason.
