Hollinger posts his advanced metrics on ESPN every now and again, so I clicked on his rookie rankings to see how Kemba stacked up with the other rookies. He was 11th in PER (Player efficiency rating), but that stat is a bit flukey depending on how many minuets you play, as evidenced by Kenneth Faried grabbing the top spot.
While Kemba was only 26th out of 33 in "True shooting percentage", his turnover rate was first or second highest, his rebounding rate was very high, and his "Wins added" and "Value added" were only third overall behind Kyrie Irving and Ricky Rubio, although, it should be said that Irving had a pretty significant lead over the rest of the field. All things considered, Kemba isn't having a bad rookie year. If he can keep getting better as a passer and hit the shots he normally makes, I think we'll view him as one of the better players from this class.
