I think Olynyk and Zeller are eruopean-profile centers. Just not strong enough to compete with NBA players. By that I don't mean just phisicaly, but mentaly as well. Soft, smooth players who can make great career overseas. Type of players like Tomi? (Barcelona) or Reyes (Real Madrid). Although, Tomi? is coming after 7 years to Utah (drafted 2008). Won't make big numbers I suppose.
