ALAMEDA -- Denarius Moore has not practiced since Aug. 4.Jacoby Ford just got out of his walking boot after injuring his left foot at Arizona on Aug. 17.Surely the chemistry Carson Palmer developed with the two receivers last year would carry over this year, no? Um, no. At least, not according to Palmer."We need a ton of work together," Palmer said. "You can never get enough work with a guy, even if hes played every rep and youve played every rep, you always need those reps. When theyre back, its not easy to get off the couch or get out of a walking boot or off crutches or whatever it may be and just show up and play."Moore, who has been nursing a strained right hamstring, and Ford were among the Raiders' six walking wounded players to observe practice, along with center Stefen Wisniewski, tight end Richard Gordon, defensive tackle Richard Seymour and linebacker Aaron Curry."He's out of the boot, so that's progress," said Raiders coach Dennis Allen. "Is he closer? Yes. How close? I'm not sure."The timing Palmer needs to get with Moore and Ford, though, is paramount to any success they hope to have. And the regular season opener is two weeks away.So yes, they need to get on the same field so they can get on the same page. Even if 19 of Moore's 33 receptions last year and three of his five touchdown receptions came courtesy of Palmer passes."This league is way too good," Palmer said. "These players are too good, these schemes are too good just to jump back in and go. So theres going to be a little bit of a process of getting their legs back and their conditioning back, but also their minds and bodies to the speed of the game to get caught up with everything."
