This seems premature to me, with both Green and Krstic unsigned FAs. Judging by actual on court production to date, Perkins scored 329 points, grabbed 426 rebounds, blocked 73 shots last season. Jeff Green and Nenad Krstic combined for nothing at all in 2011-12.
As for Fab Melo, well I have to concede Perkins rookie averages are well within reach. But when Kendrick was 22 he average 4.5 points, 5.2 rebounds, 1.3 assists, 1.3 blocks and 1.6 TOs over 72 games in 22 minutes per. I don't expect Melo to touch that. What should we wager?
