Summary: Zeller has been a solid and consistent big man during his career at North Carolina. He runs the floor as well as any true center in college basketball which shows his athleticism and effort for the a seven-footer. However, his lack of strength and physicality is a concern as he transitions to the next level. With his skill level though, he can be a solid back-up center in the NBA and should garner mid-late first-round looks.
Player Comparison: Dan Gadzuric. Gadzuric had a decent run in the NBA as a backup center, but his lack of physicality and ability to bang down low resulted in him being out of the league. Zeller is more offensively skilled than Gadzuric, but the two are similar due to their relatively solid athleticism and lack of strength. Zeller should have a longer and more productive career than Gadzuric, but has some of the same physical limitations.
It's a little strange how there are so many mocks with varying opinions of Derek Barnett where some have him as a top 10 pick, others falling outside, others have him sliding to the 20's and yet he was graded almost the same as Myles Garrett and everyone has Garrett going Top 3. I personally have Barnett as the best EDGE in the draft, and can see the case being made for either of them being Top 3 selections in my opinion. I can see Cleveland trading out of the spot again. Just strange how the opinions of Barnett vary with no solid reason as to why except "he may not produce at an NFL level the way he did in college" which is a weak argument cause I mean... isn't that true with every prospect? Has Jadeveon Clowney produced like he has in college? Nothing is a sure thing...
