After posting a 23.8 QB rating at Cincinnati in week two, Flacco responded with a pair of plus efforts. In his last two starts he's completed 46 of 68 passes for 514 yards, with four touchdowns against just one interception. 

More importantly, his confidence should be peaking after his late game heroics against the top rated Pittsburgh defense. With his tools, a confident Joe Flacco is mighty dangerous. 

All three of his wide receiver threats were involved in week four, including crunch time connections with T.J. Houshmanzadeh. 

A healthy Ray Rice or not, the Ravens are quickly transitioning into a passing team. Flacco is approaching must start territory. 

QB Sit – Bruce Gradkowski | Oakland Raiders

When Bruce Gradkowski becomes a legit fantasy option, you know NFL quarterbacking is in a desperate state of affairs. 

Despite relative success (for his standards) since replacing Jason Campbell, his performance is more a fad than a trend. 17 of his 24 completions in week four went to tight end Zach Miller and running back Darren McFadden. With Run DMC unlikely to suite up in week five, who will pick up the slack? 

Not only does Gradkowski lack the arm strength to get the ball down the field, he also lacks NFL caliber receivers to target. Louis Murphy remains questionable for week five (clavicle) and Darrius Heyward-Bey wishes he was back in the ACC. 

His greatest attribute is his legs, but you can't survive on dump off passes forever. In it's last six quarters, the San Diego passing defense has allowed a frightening 165 yards through the air. Emergency option only. 

RB Start – Cedric Benson | Cincinnati Bengals

Benson is off to a horrific start, averaging 3.3 yards per carry with a high game of 81. He's not the "make you miss" style back who can create yardage on his own. 

He needs a balanced offensive attack and good blocking upfront. Through four weeks, the opposition routinely crowded the line of scrimmage against Cincinnati forcing them to make a play down the field. 

Until last week's 371-yard explosion, they were unable to capitalize. A reinvigorated passing attack would be a blessing in disguise for Benson owners, allowing him some breathing room and holes to attack. 

He hasn't been notorious for finding the end zone, but this would be an apropo week to capitalize on a Tampa Bay defense allowing 4.8 yards per rush attempt. 

RB Sit – Matt Forte | Chicago Bears

It's important to have a short memory in fantasy football, but attempting to erase Chicago's offensive (in more ways than one) performance on Sunday night just won't fly. 

Unfortunately for Matt Forte, his O-line gives him absolutely no hope to succeed running the rock. Forte ran for 26 yards on 12 carries last week, marking his third consecutive week below 30 yards. 

He's compiled 134 rushing yards on the season (2.7 per carry), and outside of an 89-yard screen pass for a touchdown in week one, he's produced next to nothing all year. 

This is unlikely to change in week five against a stout Carolina run defense allowing 3.3 yards per rush attempt. The Panthers have only four sacks on the season, so expect a heavy dose of the passing game and more stonewalling of Forte. 

WR Start – Dwayne Bowe | Kansas City Chiefs

It’s been a brutally disappointing beginning for the talented Bowe. He’s caught seven balls through three weeks, having been targeted only 15 times. 

Quarterback Matt Cassel has been more comfortable checking down to backs and tight ends than taking deep shots with Bowe. 

Against an Indianapolis pass defense that has been susceptible to the big play, this mentality needs to change. The Colts have allowed passing plays of 61, 28 (screen), 27, 26, 22 and 21 the last two weeks. To make matters worse, they just lost starting strong safety Melvin Bullitt for the season. 

With Kansas City sporting the number one rushing offense in the NFL, it's a great time to capitalize on the play action game and open up the offense. One can only hope the Chiefs used the bye week to hatch up ways to get Bowe more touches. Head Coach Todd Haley is certainly not short on offensive innovation. 

WR Sit – Jeremy Maclin | Philadelphia Eagles

Warning: This is more a play against Kevin Kolb than against Maclin (since I can't sit two QB's, I'll sit the WR). 

Kolb has never proven himself capable of being an NFL quarterback, and following last week, it's reasonable to believe that he's not qualified. He looked entirely overwhelmed, staying in the pocket with his eyes down field for about one second, before panicking and throwing a five-yard dump off. 

He had Maclin and DeSean Jackson running free on numerous occasions, but simply didn’t have the aptitude to make the plays. Maclin caught one ball for 15 yards, and saw a measly three targets. A deep threat can only run open down the field so many times without reward before losing faith in his quarterback. 

The 49ers secondary has allowed eight passing touchdowns, but won't have to work overly hard to make Kolb uncomfortable. 

TE Start – Kevin Boss | New York Giants

No team has done a worse job defending opposing tight ends than the Texans. They've allowed 36 receptions for 410 yards to TE's through four weeks. Granted, they've faced some of the top talent at the position, but have been helpless nonetheless. 

Boss is coming off a non-impact (1 catch for 11 yards) performance last week, but is capable of big efforts on a given day. 

Even with the hyper-athletic Brian Cushing returning to the mix, the Giants will look to exploit the middle of the field at all opportunities 

TE Sit – Benjamin Watson | Cleveland Browns

Watson has quietly put up solid numbers the past three weeks, catching 15 balls for 169 yards and a score. 

He built a quick repoire with QB Seneca Wallace who likes to utilize his tight ends. 

However, with the "human interception” Jake Delhomme returning to the lineup on Sunday, Watson essentially loses all value. Delhomme has an unfortunate blind spot in the middle of the field (inability to read coverage), and prefers to attack one-on-one matchups with his outside receivers. 

When Wallace regains the starting job, Watson will return to serviceable TE status.
