I'm going to talk a little bit about the trades that have been posted as of late. It seems to me that many of the BSOTS fans are wanting the Suns to get more size to make the team more rugged. Here's one of the many problems with your posts, you're wanting to trade Robin Lopez (7-0/255) for Anderson Varejao (6-11/260) or Antwan Jamison (6-9/235) or Andrey Blatche (6-11/260) or Brandon Bass (6-8/250).
Lopez for Varejao or Blatche is swapping size for size on a somewhat equal level. But on a talent and ability level, there isn't even a question, Robin Lopez is better than both. Blatche's scoring and rebounding is higher than Lopez, but he also plays twice as many minutes. His field goal and free throw percentages are horrible. Of the 'qualified' PFs Blatche is 29th in FG% and would be last for Cs (16th for FT% of PFs and would be 8th for Cs). Varejao has a better FG% but his FT% is almost 20 points lower than Blatche (Lopez is an 82% FT shooter). But Varejao also plays almost twice as much as Lopez. Get this, while Blatche is only 24 he's a MAJOR headache on and off the court. He plays with a chip on his shoulder (and not the good type of chip) and fights with his own teammates and coaches. We just don't need that on our bench. Gortat using the media after being here less than a week is bad enough. Varejao is 28 and bound to breakdown soon. He used to be a regular on SportsCenter highlights, but without LBJ, he's non-existent any more. He doesn't impact the game offensively or defensively and is likely to be washed out of the league in 3 years or relegated to the bench. Lopez is only 22. He doesn't play a lot of minutes per night in order to keep him healthy but also because he's so young and raw. He's being developed slowly which if you don't come into the league as a Shaq or Duncan or Ewing, then as a Center, you need time to develop properly and not be rushed. Hell, even Kobe Bryant took 5 years before starting 80 games and 3 years to start 50 games and we all know Lopez is not Kobe. (In no way is this meant to imply that Lopez is the next Bryant or that he will EVER be anywhere near that level of Stardom).
Ok, so now we see we can't be considering trading Lopez for equal size. As for Bass and Jamison...why trade size that we have in a young, developing Center for an older (Jamison), smaller (Bass) forward who would again clog the SF/PF rotation even more? Neither Jamison nor Bass are going to be able to stop the likes of Duncan, Gasol, Melo, Scola, or Griffin any more than anyone else on the current team. They don't shoot extremely well, so they can't be too far from the key which will just clog that area when Nash does his drive and dish or drive and float. The Suns' system is based on floor spacing, not living in the paint.
So in review, it does not make any sense to trade Lopez for size of any player who might be 'considered' available.
