As they were winning consecutive division titles in 2008 and '09, the Cardinals regarded the 49ers as their biggest division rivals. The 49ers were awful in recent years, but still managed to win four straight over the Cardinals under former coach Mike Singletary.
This year, the franchises have gone opposite directions. Two years ago, Whisenhunt was the young, up-and-coming coach who was turning around a perennial loser. Now that's Jim Harbaugh of the 49ers.
The 49ers have been able to do this year what the Cardinals have not: in close games. The 49ers' advantage is they have a much better defense than the Cardinals. They can shut down opposing offenses when they have to.
The Cardinals have struggled with that for most of the season. And the Cardinals offense has never developed any consistency.
Quarterback Kevin Kolb has missed the last two games with a foot injury that includes a turf toe, a sprained ligament in the mid-foot and a bone bruise. He hasn't practiced in two weeks, and the hope is that he will get enough work in this week to start.
The Cardinals appear to have the luxury now of taking their time with Kolb. They are 2-0 with John Skelton starting.
Skelton has had highs and lows in his two starts. His two interceptions against the Eagles cost the Cardinals 10 points. But he also threw three touchdown passes, and he's led the team to touchdowns in the fourth quarters of both games this year.
It's not Whisenhunt's style to address a touchy issue in the hours after a victory. As expected, he brushed aside questions about a quarterback controversy, saying he just wanted to enjoy the win.
The best bet is that Kolb will start again when he's healthy. That could be another week, however. Kolb hasn't practiced in two weeks, and the most likely scenario is that he will be the backup in San Francisco.
ornerback Richard Marshall signed a one-year contract last summer, hoping for a productive season and a more lucrative deal next year. The Cardinals should be interested in keeping him. Marshall's versatility has been a boost for the Cardinals after suffering injuries to the secondary. Marshall has been the nickel cornerback all season and moved into the starting lineup for a game a week ago. With safety Kerry Rhodes out with a broken foot, Marshall has played free safety in passing situations. He has also played well on special teams.
By the numbers
Since gaining a season-high 138 yards rushing against the Giants on Oct. 2, running back Beanie Wells has averaged 2.6 yards a carry. Wells suffered a right knee injury against Pittsburgh on Oct. 23, and it affected his quickness and speed. He's had trouble bouncing runs outside, something he was effective doing in the first month of the season. Wells appears to be returning to health, however, and said he feels better than he has in a month.
--- QB John Skelton threw for a career high 315 yards against the Eagles. He was intercepted twice but also had three touchdown passes.
--- RB Beanie Wells gained 62 yards on 23 carries. It doesn't show in the statistics but Wells looked quicker and faster than he has in recent weeks. He is still less than 100 percent because of a right knee injury.
--- WR Larry Fitzgerald's two touchdowns give him 70 for his career. He moved passed Roy Green (69) into first place in franchise history for touchdowns.
--- DE Calais Campbell intercepted the first pass of his four-year career.
--- CB A.J. Jefferson intercepted the first pass of his career. He is in his second season.
--- TE Todd Heap (hamstring) has played just a few plays in the last five games.
