He is not just a stretch 4. He is also a very good rebounder. Take a look at this comparison.
His PER is lower, mainly due to a much lower USG rate. Higher TS, EF% and offensive rebound rate, relatively close total rebound rate. Higher steal and block rates. Everyone pegs Love as a max contract player/all-star-MVP candidate--and the
major difference between him and Ersan las year was that Love shot the ball more. So offensively and rebounding, Ersan is not that far off of Love if at all at the moment--and I am pretty certain he is a better defender. I firmly believe Ersan is a bargan at anything in the 10 to 11 million range.
I added Bosh to the comparison for fun:
Unless Ersan is really 28 or something--he may end up the free agent steal of the off season.
