As of now, the offensive line is a good-not-great rushing line. But would the Rams and their workhorse back benefit from having a fullback?
After rushing for almost 1,000 yards in his 14-game rookie campaign, Zac Stacy has been deemed the answer to St. Louis' question mark at running back. Daryl Richardson didn't prove to be a starting running back and Isaiah Pead the Rams saw at Cincinnati has yet to show up.
Stacy, however, proved to be the workhorse the Rams have grown accustomed to in Steven Jackson. Jackson was a consistent 1,000-yard rusher despite playing on a losing team and with injury. Several times throughout his career, Jackson played with a little more than bumps and bruises (herniated discs, broken thumb).
In the Jackson Era, the Rams had a poor offensive line and a good fullback never stayed too long. Mike Karney left after the 2010 season and since then, tight ends have been switching to fullback whenever the playbook called for one.
The Rams need to think about investing in an insurance plan via fullback. Not only would Stacy have a shield to clear the path of first level tacklers, but he would have a better chance of increasing his production throughout the season.
In 2012, Kevin Seifert, of the ESPN NFC North blog, wrote an article explaining how much Adrian Peterson benefited from a lead blocker.
He found that around 77 percent of Peterson's rushing yards came from having a lead blocker. When Peterson ran behind a fullback, he had 13 rushes of 20 or more yards. He rushed for 20 or more yards once without a fullback.
His average yards-per-carry with a fullback or lead blocker on the field? 7.2
His average yards-per-carry without a fullback or lead blocker on the field? 3.3.
I know the fullback position is not a top priority this off-season for the Rams or any team for that matter. Fullbacks are an endangered position that could easily be filled with a blocking tight end. But if the Rams can sign a good fullback in the off-season, veteran or rookie, I am confident the offense, especially Stacy, will benefit.
