He's a very talented player, but he's not even close to the best guard in Europe.
Right now those guards in Europe are all better than Shved is. I am probably forgetting several others. Guys like Llull, Greer, Seibutis, Z. Dragic, Sloukas, Gordon, Sada, Jackson, Simon, Nicholas, Siskauskas, Calathes, and Beverley are about in the same level as Shved. Shved has great potential, but not way in hell is he the best guard in Europe.
Shved is probably, I would say, the #2 young potential shooting guard in Europe right now, behind Pappas. That's his appeal. How good he is at his age and his potential.
But best current guard in Europe? No freaking way in hell. He has the potential to certainly be one of the best, but not even close as of right now. With that being said, he's not nearly as talented as guys like Navarro and Spanoulis, and I don't think even as much as Teodosic and Diamantidis. He can become a really top European guard, but not in that ultra tier of players. His potential range upside is more something like Rudy Fernandez level.
His game suits the NBA, but he's not a good fit next to Rubio.
