I disagree about Splitter. We can get into that later.
I agree Vucevic isn't there yet, but he still played 16 minutes a night for the best defense statistically in basketball last season, and played it often next to smaller defenders like Thad Young or LaVoy Allen.
Not that he's the next coming of Andrew Bogut or anything, just that he's a 7 foot rookie who is 21 years old and has already played some meaningful minutes on a playoff team. With Brand gone next season, I wouldn't be surprised if he managed 25 minutes or so a night.
