ALAMEDA -- The Raiders moved in to their temporary home at the Napa Valley Marriott on Wednesday still two rookies shy of a full draft class.

Neither first-round pick D.J. Hayden nor second-round selection Menelik Watson had signed, which isn't a cause for concern given that the first practice isn't until Friday and that signings of prominent picks are routinely put off until the last minute.

The question regarding Hayden is whether he will be physically ready to begin practice following abdominal surgery related to his earlier procedure for a ruptured vena cava last November.

Raiders coach Dennis Allen, who isn't scheduled to address the media until Friday after practice, said during the team's mandatory minicamp in June he expected Hayden to be ready to go in training camp.

Second-year guard Tony Bergstrom, who was on one of two buses that departed for Napa from the team's facility in Alameda, said he felt much more comfortable the second time around.

"That's the biggest difference, just knowing what to expect,'' Bergstrom said. "There's not a ton of surprise, and with that you can go in with a little more confidence, just knowing what's coming. We had a whole lot of extra time in the off-season workouts to learn everything, so there's really no surprises coming at you now.''

Bergstrom's message to draft picks and undrafted free agents: "Don't pace yourself, number one. That would be the No. 1 message. Come in with confidence, don't worry about what's coming up. Just take advantage of every day. It's a process, and you have to live in the process.''

Running back Rashad Jennings, vying to be the primary backup for Darren McFadden, was impressed with the training camp setup.

"This type of setting is first for me,'' Jennings said. "In Jacksonville, they did it where we were at the city-- right at the facility. I'm excited to be away a little bit and get to bond with the fellas and build upon what we built in minicamp and OTAs.''

Raiders players are scheduled for meetings and physicals Thursday before taking the field Friday morning at 8:50 a.m. The league's collective bargaining agreement doesn't allow teams to have full padded practices until the fourth day of training camp.
