Worrying about Raiders' O-line

In an Insider piece, ESPN analyst Matt Williamson looks at the position holesInsider that glared during the teeth of the preseason.

The Oakland Raiders’ woes on the offensive line qualified as Williamson’s second biggest concern. Here is some of what Williamson had to say:

The rest of Oakland's line is also quite suspect and they are switching from a zone blocking scheme to more of a power man scheme. While that fits Darren McFadden's running style much better, the switch was going to be difficult enough with guys like Mike Brisiel (a pure zone blocking guard) penciled in for a starting spot. With (Jared) Veldheer sidelined, I now expect Oakland to field the worst offensive line in the NFL -- and the rest of the Raiders' offensive personnel isn't good enough to overcome the lack of top-level blocking. As poor as Matt Flynn has been under pressure, this is even more reason to get Terrelle Pryor behind center for the Raiders.

The Raiders will be better if Veldheer can come back in the second half of the season, but I think Williamson is right. This line may be a serious problem, which will make it difficult for Oakland to overcome.
