Kelechi Osemele, Rodney Hudson impressed with Jon Gruden's energy, detail

ALAMEDA, Calif. -- Sure, the Oakland Raiders have the most expensive offensive line in the NFL, and the unit had three players selected for the Pro Bowl in left tackle Donald Penn, left guard Kelechi Osemele and center Rodney Hudson.

But the O-line, which was also one of the more curiously underachieving units in the league last season, was not a major topic of discussion at returning Raiders coach Jon Gruden's introductory media conference. In fact, Gruden was not about to break down the roster as a whole.

"I'm learning about the health of the football team right now," Gruden said. "I know they have some talented offensive linemen. They've got a gifted young quarterback. There are some real positive traits to build on, but I'm not going to make any predictions.

"I'm going to say the same things I said when I was here before -- we will get what we deserve and we will see what that is as time unfolds."

Penn, who underwent foot surgery after Game 14 and is sitting out the NFL's all-star game, played for Gruden with the Tampa Bay Buccaneers in 2007 and 2008.

But Osemele and Hudson are newbies to this whole Chucky phenomenon.

"He brings a lot of energy," Osemele said of Gruden at Pro Bowl practice in Orlando, Florida, this week. "I think that's what we need right now.

"That's the biggest change -- the energy. I think it's going to be high intensity. I think it's going to be really detail-oriented, from what I've heard. That's just the vibe I'm getting. It's going to be very, very detail-oriented, and I think it's going to be good for us."

Osemele said he was not surprised to see Gruden back as a coach after nine years in the ESPN Monday Night Football broadcast booth. "He loves football," Osemele said, "and the opportunity presented itself and so he took advantage of it."

Hudson said he only recently spoke with Gruden for the first time, and echoed Osemele's thoughts. "You could feel his energy," Hudson said. "It's not even so much [what he was] saying, but you can feel his energy. Everybody'll be ready to get back. We're going to enjoy the offseason and get back and be ready to work."

And while Hudson said he was not necessarily surprised, either, about Gruden's return, he was "sad" about Jack Del Rio's dismissal. Hudson, though, could not put his "thumb" on one reason the Raiders' season was such a disappointment.

"We obviously didn't perform as well as we liked to, for a number of reasons," Hudson said. "There was different reasons at different times. Going to reflect on it this offseason and after this offseason put it behind us and move forward."

With Gruden and his energy, obviously.
