That variety presents a daunting challenge to the opposition, which happens to be the team that beat the 49ers for the NFC championship in January, then won the Super Bowl: the Giants.
‘‘I think they've added, trick is not the right word, some scheming problems to complement what they did last year,’’ New York defensive end Justin Tuck said. ‘‘They've got some things in there that look exactly one way and it’s the complete opposite from what their play is supposed to look like. So I think their coaching staff has done a great a job of putting them in a scheme that can confuse defenses at times, but the biggest thing is just playing more physical.’’
Nowhere can an offense be more physical than in the run game.
