On Wednesday, Eagles running back LeSean McCoy got frustrated with reporters drilling him with questions about why the running game has failed to get anything going the first four weeks of the season.

With each question, McCoy admitted to being frustrated, but also insisted he remains optimistic.

"I'm confident," McCoy said. "I know what I can do. It doesn't really bother me that much. At times it can be frustrating, but I know who I am."

Despite his confidence however, the proof is in the pudding, and through the first four games, this is the worst start McCoy has ever had to his career:

2009: 162 yards on 40 carries

2010: 273 yards on 50 carries

2011: 363 yards on 66 carries

2012: 384 yards on 81 carries

2013: 468 yards on 78 carries

2014: 192 yards on 70 carries

So when will McCoy break out? It very well could be this weekend against the St. Louis Rams, and here are five reasons why you should keep riding McCoy and start him on your fantasy football team this weekend.

1) Lane Johnson

On Wednesday, the first thing that came out of McCoy's mouth when asked why he would turn it around was.....

"I got Lane (Johnson) back."

Last season's starting right tackle, Lane Johnson, finally returns this weekend after serving a four game suspension. That is big news for McCoy, as Johnson was one of the best running blocking lineman on the team last season when the running back lead the league in rushing. It also allows the Eagles to be more balanced in their approach, as they can run behind both Johnson and left tackle Jason Peters now, instead of running just to the left, which they have done more of this season.

2) Todd Herremans

Johnson being back not only helps the Eagles at tackle, but also at guard, as it allows veteran Todd Herremans to move back to his natural position at right guard. Herremans had been playing some tackle with Johnson suspended and other players injured, but now he gets the chance to move back inside. That gives McCoy his entire right side of the line back.

"I am so used to those guys," McCoy said, "and I know how well they block."

3) Ram's defense

The Rams might have a strong front line when it comes to rushing the passer, but that does not translate over into stopping the run. St. Louis is currently 30th in the NFL against the run, giving up an average of 155 yards per game.

Of the four teams the Eagles have faced this season, that is by far the worst. Three of the teams the Eagles have faced are in the top 11 against the run, and McCoy had his best day against the Jacksonville Jaguars, who are ranked 25th.

4) History

McCoy doesn't have much history against the Rams, but the one time he did face them, he had a strong game. In 2011 when the Eagles open their season on the road against the Rams, McCoy totaled 122 yards and one touchdowns on 15 carries to go along with one receiving touchdown. The two teams are very different now, but is history repeats itself, McCoy is in for a big game.

5) Chip Kelly

Last weekend, head coach Chip Kelly admitted that he didn't run the ball as much as he normally would have because he didn't trust the offensive line. That isn't like Kelly, who likes to run his offense and not be bullied into altering his game plan. Kelly is a run-first coach, and it has to be killing him as much as it is McCoy that the team isn't getting the job done on the ground.

Look for Kelly to feed the ball to McCoy this weekend after shying away from it last week, and his commitment combined with all the other factors above should lead to the breakout game many expect.
