The Cowboys defense has been the subject of nothing but pessimistic prognostications, but the team is working to find improvement over the players they kept on the initial 53-man roster.
Spillman is the more experienced of the two players and has played in every game for the 49ers over the last three seasons. The majority of that work has come on special teams, although the Cowboys probably won’t be looking down their noses at anyone who might be able to help the defense. If the 49ers are lax about securing their signals, Spilman could also give the Cowboys an edge come Sunday in the opener for both teams.
Toomer was on waivers, but the Cowboys did not claim him and will instead be signing him directly to the 53-man roster. Injuries have kept the 2012 fifth-round pick from contributing, but his ability has led to plenty of offseason notice and, again, the Cowboys need all the help they can find.
The Cowboys will need to open two roster spots with the move of defensive end DeMarcus Lawrence to injured reserve/return one possibility.
