SANTA CLARA, Calif. – The San Francisco 49ers were served a reminder Wednesday of the issues surrounding linebacker Aldon Smith, who is away from the team receiving treatment for alcohol abuse.The 49ers have vowed to support of Smith, who is 24 and in his third season with the team. But you have to wonder, if Smith's troubles persist, how long that support will remain strong. Even when he is away from the team, Smith's alleged past missteps affect the club, which is trying to carry on without its star pass-rusher.
