The problem with all of this Tsakalidis-bashing, slinslin, is that Trybanski has shown absolutely no indication that he'll be any better. In his NBA career so far, he has shown less than zero. I found a couple of exhibition (or summer league?) box scores and he was awful in those too. And it doesn't make any sense to say that he has more "potential," because he's basically the same age as Tsakalidis.
This is the same old story of the Suns expecting to find a gem in someone else's garbage. They are constantly picking up no-talent big men that another team has thrown on the scrap heap, thinking that somehow the player will magically blossom when he puts on a Suns uniform.
Tsakalidis wasn't good. Let's be clear about that. But he had spent three years learning the Suns' system, shown occasional promise, and even delivered big performances once in a while (particularly defending O'Neal). So far, Trybanski is just as old and with far less accomplishment. And to say that someone is far less accomplished than Tsakalidis is pretty low.
Regarding the Outlaw/Knight part of the deal, I could go either way on that. Neither will play much. Outlaw was a great locker room presence, but that probably isn't worth the $5.4 million he'd make next season. So that's a wash.
The problem is that the Suns forfeited Tsakalidis to the Grizzlies just to get Outlaw's 2004-05 salary off their hands. That's potentially a very high price to pay for a few million dollars. I hope that this decision doesn't come back to haunt the Suns, but I think it's quite likely that Tsakalidis will prove to be a better "true" center than anyone the Suns will have in the next five years.
