I see more Marc Gasol than I do Krstc. Krstic was slow defensively, but a solid midrange shooter and good team player. Val, one he gets more experience, I think can be a Gasol like player on defence, who clogs the middle, plays very good pick and roll defence, and above average post defence. And I already like the moves I've seen from Val on offence, as he continues to grow, he should have a good midrange shot, a good post fadeaway over his right shoulder, hook shot to his left, and a solid finisher on the pick and roll. I think Val will be in the 8.5-9.5 RPG range in his prime.
Krstic was a good player in his prime years, but I think Valanciunius has more talent and potential to be great, something Krstic never reached.
