(Betting Express) - The Minnesota Vikings had very little to celebrate during their bye week. In the game before its break, Minnesota dropped a 48-23 contest to the Seattle Seahawks. Seattle running back Shaun Alexander rushed 139 yards and four touchdowns and caught three passes for 92 yards with another score. He also set an NFL record by scoring five TDs in the first half.

In his first game after being arrested and charged with pushing a Minneapolis traffic officer with his car, WR Randy Moss struggled en route to just six catches for 50 yards, but he dropped four passes in the end zone.

"The balls touched my hands. I really don't have a word," Moss said. "The balls came off my fingertips. They bounced off my chest. I think the more I dropped, the more I got down on myself."

Is this the week that the Vikings finally get off the mat? Minnesota will host division rival Detroit and rookie QB Joey Harrington on Sunday.

The Vikings' defense has been a disaster so far. Through four games, the unit has allowed 35.3 points, 288.3 passing yards and 108.5 rushing yards per game. All three numbers are the main reason for the team's 0-4 start.

To correct that problem, the Vikings have made a few changes, including one in their starting lineup. Patrick Chukwurah will replace Jim Nelson at the strong-side linebacker position. Also, the team has decided to use Eric Kelly as the third cornerback in the nickel defense, while rookie Brian Williams will now be used as the No. 4 cornerback.

The changes can't hurt because the Vikings' defense hasn't stopped a team all year. This week, the defensive backs have to step up and make some plays, and they should be able to considering Harrington is just a rookie.

RANDY RATIO NOT WORKING OUT

At the start of the season, Mike Tice preached about the "Randy Ratio", which called for Moss to be involved in about 40 percent of the offense. It's a good plan, but in order for it to work, Moss has to catch the ball when QB Daunte Culpepper throws it to him.

In the Vikings' last game against Seattle, Moss dropped several passes. But Tice believes that game was an exception, considering the adversity Moss was facing.

"He can say what he wants to say, but I think he got so worked up and emotional about the situation that was going on," Tice said. "He was so fired up in the pre-game and in the locker room. The crowd was really on him to tell you the truth. Once he dropped the first ball, I think he lost focus, he lost fundamentals, and it just turned into one of those nightmare games for him. Yet the funny thing was, [receivers coach] Charlie Baggett told me that as much of a bad game it seemed to be for Randy, it might have been one of his better blocking games."

Tice also said that the team will continue to make Moss the focal point of the offense, but he also hopes Culpepper will look to the other receivers during the game.

"Baggett looked at every ball that was thrown in Randy's direction last year and counted them," Tice said. "He found that we threw the ball in Randy's direction 40 percent of the time through five games last year, which really isn't a lot. We won four of those five games. Thus, we came up with a term, the 'Randy Ratio.'

"Really, the ratio included about two-to-three more balls a game that we wanted to throw in the direction of Randy Moss. We felt that would help us be more explosive because a high percentage of his receptions go for long gains, it would keep him in the flow of the game, and keep him in a rhythm. However, it has hurt us as well. I have may have engraved this 'Randy Ratio' in Culpepper's head too much because he might be forcing the ball to Randy instead of coming back and hitting a back or another receiver at times."
