Despite a lack of depth in the Raiders receiving corps, general manager Reggie McKenzie said Thursday he was not interested in acquiring any of the currently unemployed veterans still looking for work.That means the not-so-Holy Trinity of wideouts Chad Johnson, Plaxico Burress and Terrell Owens are not headed to Oakland, even with only five healthy wideouts on the roster."It's not just (their) age," McKenzie told the San Francisco Chronicle and the Oakland Tribune. "If the right player could add to the groupwe just didn't feel those three were the right ones. Clear and simple. If I felt like they could have added something to what we were doing, I would have strongly considered it."Currently, Darrius Heyward-Bey is Oakland's No. 1 receiver while Denarius Moore is expected to make his season debut Sunday at Miami after dealing with a balky right hamstring since June. Then there's rookie Rod Streater, who started his fifth-round draft pick Juron Criner, who is dealing with a sore right ankle, and veteran Derek Hagan, who is still learning the playbook after signing last week.Otherwise, Jacoby Ford underwent Lisfranc surgery Tuesday that might end his season and the Raiders also have Travionte Session on the practice squad."It starts with a foundation and you have to have the guys around long enough to develop and see that development," McKenzie added to the newspapers. "And we do have a couple of guyswe were just hit with injuries at that position so early, especially with your No. 1 going down. Then, a guy like Jacoby, who we had plans for."Going into it, you felt good but you miss one guy and that can trickle down quickly. If we add guys, I want to make sure and add a guy that's going to help this team. I just didn't think those three guys were the guys."
