There are two interesting names that are available through trade at the moment -- Tampa Bay quarterback Josh Freeman and Tennessee receiver Kenny Britt.Could the San Francisco 49ers be a fit for either? The 49ers do have a need at receiver and have looked at veteran backup quarterbacks in the past month, so it's not out of the question that San Francisco would have interest. Plus, the 49ers' brass has been aggressive in the trade market and the team has a big surplus of draft picks next year.
