On this week’s episode of the Better Rivals podcast, we offer our reaction to a second shocking retirement in as many weeks, with Chris Borland choosing to hang up his cleats. We then turn our attention to the 49ers’ first week of free agent signings. Is Torrey Smith worth the richest contract Baalke has ever given to a free agent? Can Reggie Bush and Darnell Dockett bounce back from injury and churn out another productive season? Do the rest of San Francisco’s signings even matter? We answer these questions and more while grading the 49ers 2015 free agent class.
