SANTA CLARA (AP) — Alex Smith ran off the field at Candlestick Park two weeks ago to a standing ovation and cheers from the sellout crowd, not much different from the reception last January when he took the San Francisco 49ers oh so close to a Super Bowl. Now relegated to a backup role with the NFC champions, Smith's trip to the Big Easy this week leading up to Sunday's Super Bowl against Baltimore is hardly how he envisioned it. This used to be his team.
