That dropped INT was with almost 10 Min on the clock. That would NOT have been a game ender. With the way this team played in crunch time in the playoffs, there is still a decent chance they win that game. Also dropped INT by Ramsey, so "Woulda, Coulda, Shoulda".
Of Course it takes Luck to win a SB, for every team, every year. Niners D will keep them in games for sure, that is a very solid unit. If they play Lance, they will struggle against better teams. Also, Don't underestimate the difference that Wagner will make against the 9ers. Look at what Seattle has done to the 9ers run game over the last several years. I don't think the 9ers give us as much of a problem going forward. We probably win 75-80% against them over the next 2-3 years.
