Note: not to get people too excited or anything, but if we brute-force Zizic's Euroleague numbers into Hollinger's model, it projects him to average roughly 10.7 points and 14.2 rebounds per 36 minutes in the NBA. He would put up these numbers on 55.7% shooting, which would put him in the top 10 of the entire NBA.
This, of course, does not take into account any potential improvement between this season and next. Super-small sample size and all, but the numbers he's posting in the second-best league in the world are amazing.
