NFL teams are adding free agents to fill out their rosters. Seattle has signed the following players, according to the team:

• Michael Bennett, DE, Texas A&M
• Tony Fein, LB, Mississippi
• Devin Moore, RB, Wyoming
• Dave Philistin, LB, Maryland
• Andre Ramsey, T, Ball State
• Tyler Roehl, RB, North Dakota State

I'm sitting next to NFL Draft Scout analyst Rob Rang at the moment. Of the six, he singled out Bennett and Moore as players to watch.

Bennett's brother, Martellus, plays tight end for the Cowboys. Michael Bennett has the talent but hasn't always shown consistency, Rang said. Moore is a fast and versatile runner with better straight-line speed than current Seattle backup Justin Forsett, according to Rang.

I'll pass along information on other undrafted free-agent signings as I can confirm them.
