No Change: Joseph Addai Will Continue To Work Off The Bench
Addai is coming off a four-TD game against the Eagles, while rotating with veteran starter Dominic Rhodes. It's an approach that Tony Dungy said will not change. That's fine with Addai.

"I think it's helped me out a lot, not having a lot of pressure on me, not going in trying to make something happen early, but at the same time take advantage of the opportunities I have while I'm out there," said Addai, whose 789 rushing yards top all NFL rookies.

Change: Reuben Droughns Slipping Down Depth Chart
Droughns, who's been nursing a sprained foot, carried the ball twice for 4 yards against the Bengals on Sunday. He played primarily on special teams. The veteran was essentially benched in favor of Jason Wright.

Still listed as questionable with the foot, Droughns has been working with the second team again this week.

Romeo Crennel said earlier this week that Wright started only in part because of Droughns' foot -- the other part was because he liked the way Wright hits the hole.

No Change: Larry Johnson Will Continue To Be VERY Busy
In his last six games, while the Chiefs went 5-1 and vaulted into the AFC playoff picture, Johnson has been practically a one-man attack with 184 touches for a total of 920 yards and 11 touchdowns. He's rushed in that span for 845 yards.

Johnson is averaging almost 26 carries a game, which projects over a 16-game season to about 410 -- the record Jamal Anderson set in 1998 in leading Atlanta to the Super Bowl.

I'm not going to wear him out," Herman Edwards said last Friday, with a hint of impatience that the issue would even be raised. "That's what good runners want."

In fact, in an interview conducted last offseason, I asked Johnson how many carries he felt a good NFL running back needs.

"It all depends on who the running back is," he said. "Running backs like me, like when I played the Houston game [in 2005], I didn't realize I took the ball 32 times. I didn't realize that because my body just didn't feel that way. It's different for each running back.

"But to me it feels like I need to have 32 touches just to feel like I'm doing something."

Based on his effort to date this season, who am I to argue?

Change AND No Change: Raiders Replace Offensive Coordinator
Art Shell fired offensive coordinator Tom Walsh on Tuesday, leaving this week's opponent, the Texans, wondering what changes tight ends coach John Shoop will make now that he has been promoted to replace Walsh.

The better question might be what kind of impact can he make?

Oakland has scored a league-low 132 points this year and is assured of a fourth straight losing season for the first time in franchise history. The Raiders were last in the league in passing offense and total offense, and 21st in rushing offense.

Oakland has just 10 offensive touchdowns all season, less than half of LaDainian Tomlinson's individual total for San Diego. The Raiders have allowed a league-high 53 sacks -- 10 more than second-place Cleveland -- and are the only team in the league gaining fewer than 250 yards per game, with a 239.8 average.

Given their limited personnel, apparently pervasive attitude issues and sundry other problems, it's hard to imagine a change of coordinators making an immediate difference. It might provide a short-term spark, but the Raider offense isn't suddenly going to hit stride down the stretch.
