KG was our center. KG hasnt played PF for years.
Doesn't that depend on the dubious definition of what is a 'center' versus what is a 'power forward'?
Just because he was the taller player on the floor, does that mean he was the 'center'?
Is he the 'center' when he's playing offense out near the top of the key? Is he the 'center' when he plays most of his defense along the free throw line?
FWIW, according to his positional splits at 82games.com, KG spent 4% of his minutes last year at power forward. And in the 2011-12 season he spent a third of his minutes at power forward.
Not that their definitions are likely any more dubious.
