The Giants have signed veteran offensive lineman Shawn Andrews. Andrews, a former Pro Bowler with the Eagles, has spent the last 10 months rehabbing his back in Los Angeles. Andrews signed a six-year "prove it" deal with a lot of consideration in the second year according to his agent, Rich Moran. "I'm laying it all on the line," Andrews said. "Not that I haven't before but this is it. The Giants are going to get everything from me."
