Two games into the season and the Giants are in must-win mode. Giants can’t afford to open the season 0-3 and even think about making the playoffs. It’s hard enough to regroup after an 0-2 start, so winning at Houston on Sunday has to happen. When the Giants figure out their offensive line, will be the week they starting winning games. Giants have some of the best playmakers in the league, but if quarterback Eli Manning doesn’t have enough time to get them the ball, it doesn’t matter.
