NEW ORLEANS -- San Francisco 49ers head coach Jim Harbaugh, offensive coordinator Greg Roman and quarterbacks coach Geep Chryst get credit for helping quarterback Alex Smith turn around his career.While they surely played a role, something Smith said Tuesday from Super Bowl media day caught my attention. I wondered if it represented a shift as Smith, benched as the 49ers made their Super Bowl run, recasts himself for future employers as more than a product of the 49ers' successful system.
