SAN FRANCISCO -- Quarterback Alex Smith and running back Frank Gore arrived in 2005. The next year, the 49ers selected tight end Vernon Davis.The 49ers' unfathomable 36-32 victory over the New Orleans Saints on Saturday at Candlestick Park was understandably emotional. And those emotions did not just being for Davis after his game-winning touchdown catch and cry-on-the-shoulder moment with coach Jim Harbaugh.Davis spoke to his teammates at halftime to let them know that this moment could not get away."It was very emotional," Davis said. "One shot. That was the message. We have only one shot and if we don't take advantage of it, we go home. There was a lot of fire within me at that moment."The 49ers defense has carried the team all season. But the 49ers defense allowed a couple of big-play touchdowns in the fourth quarter. Twice, the 49ers looked to be in dire situations."I think we got too excited," Saints running back Darren Sproles said. "We didn't think they could score like that, but they did. They proved us all wrong."Alex Smith.Vernon Davis.Frank Gore.The three players who came into the league within a year of each other experience plenty of frustration together.
