Hour 1: Greg Silver & Larry Krueger open up Friday by reacting to yesterday's news of Dre Greenlaw returning to the 49ers on a 1-year, $7.5 million deal. The guys take your calls and ask whether or not you like this move for the offseason, or if Greenlaw's recent injury history is the exact thing that this team should avoid. They also discuss the signing of cornerback Nate Hobbs, who has shown promise but also struggled to stay on the field in Green Bay last season.
