If the Tall Blacks have depth in the front court, the point guard position is an ongoing area of concern for Vucinic though.
"What we have identified is we are maybe a little thin in the guard line. Tai [Webster] boosts our stocks in that regard when he arrives on Monday. He was with us a couple of years ago and has enjoyed a good season with Nebraska and we are hoping that he comes back in good shape and good form and is able to slot in quickly."
There is also an intriguing battle developing between big men Casey Frank and Nick Horvarth.
"Nick and Casey are battling for the one naturalized spot, but that doesn't mean we will eventually have a naturalized player on the team for Spain, they still have to fight for a spot on the team," Vucinic said.
Centre Rob Loe won't play during the Korean series as he is playing in the NBA's Summer League in Las Vegas.
Vucinic will confirm his final 12-strong squad on the eve of the World Cup which gets underway on August 30 with the Tall Blacks' Group C opener against Turkey.
