2. Seymour's defense not up to par
Anchored by ex-Patriot defensive tackle Richard Seymour, the Raiders line isnt something to take for granted. Seymour, who played eight seasons in New England, is averaging close to a sack per game (2.5) at age 31. But without cornerback Nnamdi Asomugah, the Raiders lack a shutdown corner, and Tom Brady could expose that weakness Sunday by targeting other receivers besides Wes Welker. The Raiders have allowed the 28th most passing yards this season, averaging 290 per game.
