The Giants haven't had a great return game in a long time. Domenik Hixon and Jerrel Jernigan have showed flashes of excellence as returners, but both are currently injured, and either Danny Ware or rookie Da'Rel Scott will start at returner against the 49ers. Whoever does needs to make himself known.
The Giants have always relied on the run more than the pass, but they will not have the luxury of a powerful ground game against San Fransisco, which means kick and punt returners will have to work hard to give New York good field position. Otherwise, the Giants will be looking at many long, difficult drives.
However, the Giants need to work on more than their return game. They also need to contain Ted Ginn, one of the league's most dangerous kick and punt returners. He has already taken back a kick and a punt for a touchdown so far this year and is an explosive playmaker.
In what is sure to be a close game already, the last thing the Giants need is for Ted Ginn to take one to the house. They also don't need a return game that sets them up on the 20 every drive. Special teams will play a key role in the outcome of Sunday's game, and New York needs to dominate San Fransisco on it.
