An early look to Week 2 of the 2011 season...The Raiders visit Buffalo with a chance to go 2-0 for the first time since their Super Bowl season of ’02, the franchise’s last winning campaign. More importantly is another stiff test for the Bills’ defense, which finished dead last in the NFL against the run last season but looked better in a 41-7 win at Kansas City. While the Chiefs did get 108 yards on just 18 carries (6.0 avg.), it was a far cry from the 274 yards rushing on 45 carries that Kansas City (the league’s top rushing offense in 2010) amassed in a Week 8 overtime victory over Buffalo last season. Meanwhile the Raiders, which gained the second-most yards on the ground last season) comes off a 190-yard rushing effort Monday night at Denver… <!--more-->Ken Whisenhunt’s club heads to Washington in a battle of 1-0 teams that got good performances from their quarterbacks last week but also an honest effort from their ground attacks. Both the Cardinals (25) and Redskins (26) totaled 25-plus carries last Sunday, perhaps a good sign for the 2 teams with the fewest rushing plays in the league in 2010. And keep an eye on Redskins’ RB Tim Hightower, late of Arizona, who ran 25 times for 72 yards in Washington’s 28-14 victory over the Giants…The Saints brought in their share of new faces on defense, most notably on the defensive line with DTs Shaun Rogers and Aubrayo Franklin, but there’s obviously still some work to be done after the 42-34 loss at Green Bay on opening night. New Orleans gave up 399 total yards and Packers’ QB Aaron Rodgers threw 3 touchdown passes in the first quarter to set the tone for evening. Including the playoff loss at Seattle, Sean Payton’s team is just 1-4 in its last 5 games dating back to last season, this after rolling off 6 straight wins in November and December. And the fact that the Saints have scored 36 and 34 points, respectively, in theirlast 2 outings and lost can’t make Payton happy…Different head coaches and coordinators and different systems, but it’s hard not to notice the improvement made by the Lions’ offensive line the past year-plus in terms of pass protection. Jim Schwartz’s club did not give up a sack in last week’s win over the Buccaneers and has surrendered just 27 sacks in its last 17 games dating back to the start of last season. Compare that to the totals of 63, 54, 52 and 43 from 2006-09, respectively, and you can see the team has made strides. Ofcourse, one factor for the improvement may be the fact that the Lions’ offensive line now practices against the likes of DTs Ndamukong Suh, Corey Williams andDE Kyle Vanden Bosch…
