Heat, Kings and Grizzlies still have work to do

The free-agent frenzy is over, and a number of high-profile teams have a lot to show for it. With NBA spending at an all-time high and trades going down at a frantic pace, there is a growing parity in the league that gives hope to franchises that have had little to cheer about the past few years.

From Boston to Utah to Orlando and even Cleveland, GMs can stand up credibly after a busy summer and tell fans hope is on the way.

With all the focus the past two months on what teams have done in an effort to improve, it's just as instructive to look at what some teams have left to do.

Today, Insider takes a look 10 teams that still need to make another move or two before training camp begins. Do the Heat have enough depth to make Shaq happy? Can the Kings add enough depth to make a difference in the West? Will the Grizzlies finally get their hands on a big man? Here's our take.
