Kyle Boller signs as backup quarterback

For weeks, the Rams appeared on the verge of signing veteran Gus Frerotte as the backup quarterback to Marc Bulger. But the Rams grew tired of waiting on Frerotte, and wasted little time signing his replacement.

Just a few hours after completing their first minicamp under coach Steve Spagnuolo, the Rams signed former Baltimore Raven Kyle Boller to a free-agent contract. It's a two-year deal but further contract details weren't available.

"We think he's a good fit for us backing up Marc," general manager Billy Devaney said. "He's a young guy that still has a ton of ability and a lot of upside. This is a really good pickup for us."

The Rams' depth chart at quarterback now includes Marc Bulger, Boller, Brock Berlin and Jeff Otis. Boller has started 42 NFL games, all with the Ravens. He spent last season on injured reserve with a shoulder injury. If healthy, Boller should serve as a viable backup. He is also relatively young -- 27 -- so he has more upside than the 37-year-old Frerotte.

Opinion: Rams made the right move on signing Kyle Boller rather than the aging Gus Frerotte.
