ALAMEDA -- No doubt with starters Ron Bartell and Shawntae Spencer injured, the Raiders are thin at cornerback. So thin that Oakland signed Brandian Ross off Green Bay's practice squad and starting free safety Michael Huff took some snaps at corner on Wednesday.So how comfortable, or uncomfortable, is coach Dennis Allen with the Raiders' current depth at cornerback?"Listen," Allen said, "it is what it is. Our deal is, weve got NFL football players and we got to go out and play at a certain level and we hold all our guys accountable at the same level."Currently, the Raiders have healthy cornerbacks in Pat Lee, Joselio Hanson, Philip Adams and Ross. Even Coye Francies was out with a concussion suffered Sunday in Miami.So the Raiders even considering moving Huff to a corner makes some sense."Hell probably take some reps there this week," Allen said.So what makes Huff so unique among safeties that he might be able to make the move?"Speed and athleticism," Allen said. "Thats the biggest thing. Youve got to be able to run and play out there on the edge and he can certainly do that."There had been rumblings out of Hue Jackson's staff that they were considering switching Huff. And this regime?"No, no," Allen said. "That really wasnt a consideration."What made the Raiders consider Ross, though, was his physicalityand the familiarity general manager Reggie McKenzie had with him from their days in Green Bay together."He's a big guy (and he) has got some coverage skills," Allen said. "He's a guy that Reggie knew from being there with him, so he was a guy we thought could come in and compete."Ross said he planned on playing against Pittsburgh on Sunday, regardless of any learning curves."It's just different fronts," Ross said. "As far as coverages, coverages don't change that much throughout the league. It shouldn't take long."That's the plan -- try to pick up (the schemes) ASAP so I can help get this first 'W' here."Said Allen: "I think well have to wait and see how this week plays out. I dont know that right now just because today was kind of the first day he came out to practice. So were going to evaluate that as we go through the week and see where hes at."
