Last year, the San Francisco 49ers signed Nnamdi Asomugha and toyed with the idea of adding Charles Woodson.Clearly the team has no problem considering aging defensive backs. That leads me to wonder if, under the right circumstances, if the 49ers will have interest in Champ Bailey.The future Hall of Fame cornerback was released by the Denver Broncos this week. Bailey, who will turn 36 in June, has said he still wants to play. Even though Bailey is fading, he can still help a team.
