NAPA — Stefen Wisniewski has every reason to believe he'll be the Raiders' starting center for a second straight season despite talk about a possible move to left guard.
If his first two years in the NFL have taught the 2011 second-round pick anything, it's to be prepared for change — even if coach Dennis Allen insists there are no plans to move him.
"I haven't been told that by anybody," Wisniewski said Thursday after the Raiders resumed training camp practice following an off day. "I'm just working to be the best center I can be."
Wisniewski has already played for two head coaches and three line coaches. He's also in the process of learning his third offensive system.
Finding stability in the running game has been equally challenging for the Raiders. That's why so much attention is being focused on their offensive line.
The team also signed five-time Pro Bowl lineman Andre Gurode last week and have him taking reps at center and both guard spots.
For now, Wisniewski remains atop the depth chart. He started 15 games at center a year ago after missing much of the offseason due to shoulder surgery, and expects to be back there when the 2013 regular season begins.
"As far as I'm concerned I'm playing center now," Wisniewski said. "If that changes, I'm sure they'll let me know. But I'm happy where I'm at. If they want me to play guard, I'll play guard. It is nice to get to stay in one spot, though, and get comfortable there."

Ford, who missed all of 2012 with a foot injury, jogged from the locker room to the practice field but remains sidelined. ... Former Raider linebacker Bill Romanowski and offensive lineman Lincoln Kennedy attended practice.
