Around the NFC West: Jan. 29, 2013NEW ORLEANS -- Word came Monday from Pro Football Talk that San Francisco 49ers backup quarterback Alex Smith would request his release following the season.My initial thought: Good luck with that.Players in Smith's situation naturally would prefer to receive their release over a trade for the freedom it would provide them in seeking their next employer.But if the 49ers can get value for Smith by trade, they have a professional obligation to seek that value for the future of the team.
