Seahawks hope Eddie Lacy can help resurrect physical run game

Lacy shakes up free agency by signing with Seahawks (0:57)

Adam Schefter details RB Eddie Lacy's one-year, $5.55 million deal with the Seahawks. (0:57)

Coach Pete Carroll made it clear after last season that he wants the Seattle Seahawks to fix their run game this offseason.

In 2016, the team's running backs averaged just 3.83 yards per carry (24th in the NFL). After doing their homework on a number of veterans, the Seahawks have settled on adding Eddie Lacy, a former Packers running back.

Terms: One year, $5.5 million ($3 million guaranteed)

ESPN 150 ranking: No. 30

Grade -- B: The most attractive part about Lacy's game, as it pertains to fitting with the Seahawks, is that he can gain yardage even when the blocking is far from perfect. Since entering the NFL, Lacy has averaged 2.15 yards after contact, which ranks sixth-best over that span. The Seahawks' biggest question mark is their offensive line, and they're hoping Lacy can make up for some of the issues up front. Lacy has shown he can carry the load, totaling 717 carries from 2013 to 2015. Investing big money in veteran running backs is often unwise, but Lacy will be just 27 at the start of next season and is under contract for only one year.

What it means: Lacy is the favorite to carry the load for the Seahawks in 2017. Carroll has said often that his preference is to go with multiple backs, but with Marshawn Lynch, the Seahawks had one workhorse. Lacy joins a backfield that includes Thomas Rawls and C.J. Prosise. The coaches still like Rawls, but he missed seven games last year due to injuries and averaged just 3.2 yards per carry. Carroll has said that Prosise needs to prove he can be durable, but the team is excited about using him as a third-down back who can create mismatches in both the run and pass game. Given that Lacy is signed to only a one-year deal, the Seahawks could still use draft capital on a running back. This signing puts last year's fifth-round pick, Alex Collins, squarely on the roster bubble.

What's the risk? Lacy has battled weight issues during his NFL career and was publicly called out by Packers coach Mike McCarthy in 2015. He got in great shape last year and averaged 5.07 YPC on 71 carries through the first five games of the season. The Seahawks will have to make sure Lacy stays in shape, but durability also is a bit of a concern. Lacy will have to prove that he can be effective coming off last season's ankle injury that sidelined him for 11 games. But in his first three NFL seasons, Lacy missed just two games.

The Seahawks' run game works best when QB Russell Wilson is healthy, the line is blocking well, and the back can pick up yards after contact. The Seahawks are counting on Lacy to help with that third factor. But if the offensive line doesn't improve, it might not matter who the back is.
