This year's NFL free agent period will officially begin next week on Tuesday, March 12. There are plenty changes abound in the Bay Area, as the San Francisco 49ers are expected to let a number of their unrestricted free agents walk outright. All-Pro safety Dashon Goldson headlines the group, but he may be just one of many.

Randy Moss and Ted Ginn Jr. are two more contributors that are on their way out. This does create a need at wide receiver, and with Ginn on the chopping block, the 49ers will be minus a return specialist.

When Ginn first joined the 49ers, there was the hope that he could develop as a receiver. But when San Francisco came to terms with his limitations, the former first-rounder became an electric returner.

He was extremely valuable in 2011, when Jim Harbaugh and company saw first-hand how important it was to have dynamism on special teams. He played integral roles in wins against Seattle and Detroit that year. Unfortunately, Ginn lost his touch this past season and saw almost no time on the field.

This now puts San Francisco in a position where they have to look to add competition.
