My only point is, I think Zeller and Koufos are the same person.
Koufos last year averaged 16.6 minutes, 5.2 points, 5.3 rebounds, .8 blocks per game. Two years ago, when Zeller was not starting for Cleveland, 15 minutes, 5.7 points, 4 rebounds, .5 blocks per game.
In 12/13 Koufos as a starter did 22 minutes 8 points 6.9 rebounds 1.3 blocks per game. This was his 6th year in the league. Last year as a starter, Zeller did 21 minutes, 10.2 points, 5.7 rebounds, and .6 blocks per game. This was his third year in the league.
I think Zeller is ahead of Koufos and younger.
