you can´t be serious man, I see the rebounding numbers of an eurolegue proven 24 year old BIG-MAN like Pekovic who averaged on 13 minutes 3 rebounds per game, in his first NBA Season. And I see a Kanter boy who was comin into the league with a big leck of playing time (almost 2 years not played in a real competition), who averaged 4.2 Rebounds on 13 minutes playing time.
I see Kanter as a player who can easily average like 20+ and 10+. Just look at Omar Asik from turkey even he is averging 12 boards per game in 30 minutes and Kanter is a much bigger rebounding talent than him.
@Edit:
Mirsat Turkcan who was the best euroleague rebounder of all time, said that Kanter was the most talented rebounder he has ever seen.
