"That's who he is," Kiffin said. "The thing about Zach, you're not going to have to worry about he's going to come back out of shape or that he hasn't been working out, and that's part of what went in to drafting him. He's a great competitor. He always has been all the way back to high school. He's a guy who's going to give it up for you and the type of guy we're looking for."
Miller had spent the past few days in Oakland waiting for his agents and the Raiders to iron out a deal. The two sides nearly had the deal completed Thursday but it wasn't until the following day -- after Miller had missed the first practice -- that the details were finalized.
"I wanted to be here for the first practice but it just didn't work out," Miller said. "I just have to make as many plays as I can … so they have to make me the starter."
Meanwhile, little movement was made in negotiations with Russell. The No. 1 overall draft pick remains in limbo while the team and his representatives continue working on what will be the most lucrative contract the Raiders have ever given a player.
"He's still not here," Kiffin said. "(We're) making movement on his contract but obviously not there yet."
