From Tim Chrisolm

Did you know that Ed Davis was leading the Toronto Raptors in PER? After spending two seasons hovering around the league average, Davis has jumped up to a 20.8 rating early this season, and that has put him in the top-ten amongst NBA power forwards. That means that Davis has a higher Player Efficiency Rating than Kevin Garnett, Zach Randolph, Paul Millsap, Kevin Love and Serge Ibaka - the next five guys on the list.

He goes on to point out the limited minutes and how Ed needs to prove himself in heavy minutes now but it is a pretty good stat. More evidence pointing to Ed Davis as the future of the Raps at power forward.
