The core of the Miami Heat, Dwayne Wade, Lamar Odom, Caron Butler, Rasual Butler, Udonis Haslem, and Malik Allen will return next season but beyond that, Riley  isn't sure how the off-season will unfold.

"We like our base, this core of young, enthusiastic, energetic, good talent and so we're not looking to shop that," he said. "We're looking to augment it, and there's other ways to do that before you have to give up something."

The main focus of that core is Dwayne Wade.

"The fact that he developed so quickly with his confidence level and maturity and everything, it just sort of blew my mind," Riley said of Wade. "I've never had a player that I've ever drafted that was as good as Dwyane is in his first year."

As for the rest of the players and how the off season will play out?

"We need a lot more work," he said. "Let's not be naive here. We had a nice run to the second round of the playoffs, but this team is flawed. It's flawed in the right way because it's flawed with some talent. So we've got to move some pieces, keep experimenting, add some pieces to it, and not dig into the core."

As for pursuit of a big man, Riley said he's not sure if the Heat will get that done with its first-round pick (No. 19), using the $5.1 million mid-level exception, the $1.6 million exception or through a trade. But he knows what he wants.

"It's size," he said. "I think this team would benefit by having a little more size to protect the versatility of our athletes in a lot of ways -- screens, taking charges, defensive rebounding, kicking it out, trailing on the break."
