Jeff Fuller, Cameron Marshall to Seahawks: Latest Contract Details, Reaction

The Seattle Seahawks signed two former Canadian Football League players Thursday, wide receiver Jeff Fuller and running back Cameron Marshall, per Curtis Crabtree of Pro Football Talk.

Seattle has had the NFL's best defense over the past four seasons, but the offense is a work in progress. Finding a running back became a necessity when former Pro Bowler Marshawn Lynch announced his retirement at 29 years old this week, per Crabtree, leaving Thomas Rawls as the only running back on the active roster for next season.

Fuller hauled in 47 passes for 619 yards and three touchdowns in 13 games for the Calgary Stampeders last season and is the second CFL pass-catcher to sign with the Seahawks in three years. Chris Matthews, who came from the CFL, had just four receptions in 12 regular-season games with Seattle, but he had 109 receiving yards and a touchdown in Super Bowl XLIX.

If Fuller, 25, could duplicate those numbers, it would be a great signing for the Seahawks. The 6'4'', 223-pound receiver started off on Calgary's practice squad in 2013 but played his way onto the active roster, per Andrew Bucholtz of Yahoo Sports.

One of Fuller's former Calgary teammates, quarterback Bo Levi Mitchell, congratulated him after the news broke:

"

Good luck to Jeff Fuller, who will kill it in Seattle. Couldn't be more excited for the journey ahead for him and E! https://t.co/YaE4zExfnl

Seattle could expect more from Marshall, 24, because of his position. He rushed for 614 yards and eight touchdowns last year but played in six more games than Fuller. Here are some highlights, courtesy of Marshall, who finished his Arizona State career with 2,700 yards and 38 touchdowns:

It's never easy to tell whether a CFL career will translate into a successful NFL career, but the Seahawks have already proved it's possible—and they need help on offense. With Russell Wilson under center and a stout defense mainly intact, Seattle should be one of the top teams in the NFC again next season.

If either of these two signings produces a diamond in the rough, the Seahawks would be that much tougher to beat.
