Williams, a streetball star, has an arsenal of offensive moves honed on the tough playgrounds of New York City.

The physically imposing guard is near unstoppable one-on-one and Wollongong coach Eric Cooks revealed Franklin will be given the unenviable match-up.

Cooks said the influence of streetball was obvious in the way Williams attacks the basket.

"He's really high-skilled in the on-on-one individual game that's the streetball game, one-on-one," Cooks said.

"He's probably at his best in transition, he's very skilled at handling the ball and getting to the basket."

Wollongong will try and force Williams into taking outside shots. The 191cm guard is averaging 19.4 ppg this season but just 16 per cent (one from six) from beyond the arc.

"I guess one of the deficiencies in his game is his perimeter jump shot. He's not excellent at the three-point shot but he's so quick, he's still hard to keep out of the paint," Cooks said.

"We don't want to give him too much time, but if we have to choose between him making a jump shot or getting to the basket, we're going to take the perimeter shot."

Hawks captain Matt Campbell had been drawn the defensive assignment on Williams in the past, and had some success in slowing him down.

But the veteran guard said a team effort was required from the Hawks to limit Williams' opportunities.

"The best way to guard him is by team defence. I think that's how you stop him, as a team individually I think he's too good to stop completely," Campbell said.

"He's ridiculously quick and strong, he's like Kavossy, he has that same sort of strength that Kavossy has, plus the quickness.

"He grew up playing streetball, he's played one-on-one all of his life, so he reads his defender really well. If you step too far to one side he knows what to do to get you to commit a little bit further. He's just real tough in that way, just really hard to keep in front if you."
