8. Dashon Goldson: It is unclear whether or not the San Francisco 49ers will re-sign Dashon Goldson, who at 27 is currently entering the height of his pro career. The 49ers need all the help they can get at safety, but there is not enough cap room to ensure Goldson's signing. Goldson was named to back to back Pro Bowls, as well as an All-Pro team for his spectacular season in 2012. Clearly, Goldson was successful enough in order to lead his team into the Super Bowl, so other teams will be eager to scoop him up if San Francisco does not.
