The Raiders showed a surprising command of the line of scrimmage on both sides of the ball. McFadden and Bush ran for 190 yards. McFadden ran for 150 while Bush made the tough, short yardage runs. On defense, Orton was pressured repeatedly and sacked four times. Special teams was, well, special too. Janikowski kicked a 63 yard FG (the game was in Denver) and Lechler gave the Raiders good field position on several occasions.
Frankly, the Raiders performance was, in many ways, as surprising as that of the Bills. The Bills will need to repeat and perhaps exceed their showing against the Chiefs. The Raiders looked considerably more formidable than the Chiefs.
There were Raider weaknesses. The Raiders committed 15 penalties and played some sloppy football. They were unable to mount much of a passing attack with only 99 passing yards. If the Bills can maintain their error free execution and the Raiders continue to make mistakes, the Bills may again have the "strong possibility" of a win. In any event, it shapes up to be a much more interesting contest than it appeared to be several weeks ago. Go Bills.
