St. Louis (0-5) @ Baltimore (3-2) This game is likely to be a battle of attrition, as both teams are suffering from the injury bug--a virus that is wreaking havoc through the NFL this season. Which team comes out victorious will be the team that gets inexperienced players to play the best above their proverbial heads. One team is desperate for their first win of the season; the other is desperate for a score that does not come from a kick of the ball. How They Match Up: Rams' offense vs. Ravens' defense: Frerotte will lead the Rams' 27th-ranked offense, averaging 287.4 total yards per game, against Baltimore's fourth-rated overall defense. In two games (one started), he has completed 55.1% of his passes for 281 yards, with three touchdowns and three interceptions: a passer rating of 67.6. Just who will be catching passes from Frerotte is the question of the day. Wide receivers Isaac Bruce (15 catches, 203 yards), Torry Holt (28 catches, 351 yards, 3 TDs) and Drew Bennett (8 catches, 94 yards, 1 TD) are banged up and will be game-time decisions. One of the replacements, Dane Looker (3 receptions, 19 yards) is out for the game, and Dante Hall (4 receptions, 27 yards), who is also the return specialist, is likely a game-time decision as well. If Hall cannot go, first year receiver Marques Hagans (1 catch for 11 yards) will fill in at wideout and will return kicks. Tight end Randy McMichael (12 catches, 146 yards, 1 TD) is likely to be the only experienced healthy body in the passing game. Rookie Brian Leonard will lead the 21st-rated rushing attack of the Rams, averaging 91.6 yards per game, against the second-ranked run defense of Baltimore. He is taking over the backfield duties for injured starter Steven Jackson; he has carried the ball 38 times this season for 181 yards, plus 12 receptions for 75 yards. St. Louis has given up 13 sacks, is averaging a time of possession of 29:22, and averages 14 points per game. Baltimore's defense has allowed an average of 207.4 yards per game through the air, while giving up eight touchdowns to four interceptions, in addition to nine sacks on the season. Against the run, this unit is giving up an average of 66.6 yards per game, 2.9 yards per carry, and just one touchdown. They allow an average time of possession of 25:16, and 19.4 points per game. Ravens offense vs. Rams defense: Steve McNair is scheduled to make the start for Baltimore's 11th-rated total offense. McNair has completed 65.6% of his passes for 885 yards with two touchdowns, to two interceptions, in four games. He is listed as a game-time decision and, if he cannot make the start, Kyle Boller (33 of 51, 287 yards, 2 TDs, 1 INT) will lead a Ravens offense that has averaged 233 yards per game through the air (10th). Derrick Mason leads the club, and the league, with his 44 receptions, and leads the team with 372 yards and one score. Mark Clayton (10 catches, 81 yards) and Todd Heap (19 catches, 201 yards, 1 TD) are working through a host of injuries. Demetrius Williams leads the team in average yardage per reception, 13.9, on 16 catches for 222 yards. Second year tight end Quinn Sypniewski has 12 receptions for 80 yards, and one score. Willis McGahee leads the Baltimore rushing attack, which averages 113.2 yards on the ground (14th). McGahee is currently third in the league in yardage, with 464 yards on 102 carries (4.5 yard average) and adds 143 yards and one touchdown on 18 receptions. Overall, the Ravens are second in the league in time of possession, at 34:44, but are averaging just 17.6 points per game (21st). The Rams will counter with the league's 27th overall defense, which allows 356 total yards per game--210 yards per game through the air. Quarterbacks are completing 60.7% of their passes against St. Louis, while throwing seven touchdowns to three interceptions. The Rams have generated seven sacks. St. Louis allows teams an average time of possession of 30:38, and 27.4 points per game. Overall: The Ravens own the NFL's best record at home since 2000, compiling a 44-14 mark, including a seven game regular season home winning streak. They are 1-2 against St. Louis, including an 0-2 mark under head coach Brian Billick. In two road games this season, the Rams have been outscored 59-10 and have been outgained 824 yards to 432. In five games, Baltimore has scored just seven touchdowns, including a 5-for-16 mark in converting redzone opportunities into touchdowns. Whether it is McNair or Boller starting at QB on Sunday, the Ravens must solve the riddle that is keeping them out of the endzone. more here-
