Here's where we stand at the moment:
Rondo, House, Pruitt (?)
Ray, Giddens, TA
Paul, Walker
KG, Sheed, Scal
Perk
1. We need to get a wing backup. Our best option at the moment is Grant Hill, but if he doesn't sign with us, our options are narrowed considerably. We're left with Keith Bogans, Von Wafer, Marquis Daniels, Matt Barnes, or somebody similar. Either that, or we make a trade with a team that has an excess of wings and money problems (like NO).
2. We need to fill the 4th big spot with a guy who can play 10-15 mpg. Ideally we resign BBD, but otherwise we could sign a decent F / C like Chris Wilcox, Drew Gooden, or Rasho Nesterovic.
3. We need to get a backup PG - somebody who can play around 10 minutes a night without turning over the ball a lot or getting burned on defense. Ideally it would be somebody who is at least 6'3'' who can defend SGs so House can play at SG. Bobby Jackson is the first guy that comes to mind, but apparently the Celtics are looking at Tyron Lue (eh). Pruitt might be a possibility, but things aren't looking too promising on that front.
That's 3-4 signings we need to make before we're a complete team. The only one I'm concerned about at this point is #1. The other two should be pretty easy to solve. Whether we resign the guys we've already had (BBD, Pruitt), or sign a guy for the minimum (i.e. Wilcox and Jackson), we should be fine. As long as our core bench is House, Rasheed, and a solid wing backup, it doesn't really matter who the other two guys are.
