This is just a theory of a recently released player by the Raiders.
Now I do not have a clue to why Sulak or Joseph were waived before training camp. My thoughts on Joeeph was that he was going to be a great run stopper for The Oakland Raiders. Not someone that would be waived before training camp started. Sulak; I really don't know that much about the 6th round pick.
As far as the release of Keith Davis; I came to the conclusion that he was released for making prior comments about who he felt should be the starting QB for Oakland this up comming season. On June 15, 2009, Davis made the statement on Sirius Radio, that he felt Jeff Garcia gave the Raiders a better chance to win based on the experience of Garcia rather than starting JaMarcus Russell. I don't think this went over well with the organization as a whole. In order to have a good situation in the locker room, there has to be support from fellow players. It's my opinion that he started a division in the locker room before camp started, and that is the reason why he was released.
Now I don't know if this is fact; Its just my opinion.
