Only two teams allowed more rushing yards than the Giants did last season, and there wasn't one that allowed more than the Giants' 4.9 yards per carry. Tom Coughlin spoke after the season about his team needing to win more at the line of scrimmage, and on defense that starts on the defensive line. The Giants made two moves in the offseason that should immediately help the team's run defense. They signed 6-4, 346-pound Kenrick Ellis, a former Jet who will help solidify the Giants defense up the middle. He is known as someone who can take on multiple blockers and occupy the middle of opposing offensive lines. At defensive end, the Giants added former Dallas Cowboy George Selvie to their ranks, signing him as a free agent in March. Selvie is known as a good run defender but also has 10 sacks in his last two seasons.

Johnathan Hankins, who had a breakout year with seven sacks in 2014, wants to continue to improve as he quickly develops into one of the best defensive tackles in the league. He not only has the strength to be stout against the run, but he can also collapse the center of the quarterback's pocket using his quickness and power.

Few things are more valuable to a defense than inside penetration.

The Giants boast good veteran depth at defensive tackle as well, with Cullen Jenkins getting ready for his third season with the Giants. Jenkins battled through a myriad of injuries in 2014, but with 12 NFL seasons under his belt, he still provides steady production and much needed leadership.

Markus Kuhn enters his fourth season as a member of the Giants after contributing as a rotational player in 2014. He provides more veteran depth at tackle. One other player to watch is Jay Bromley, the Giants 2014 third round pick out of Syracuse. At 6-3 and 310 pounds, he looks the part of a defensive tackle, and he will try to bring his great college production to the NFL level in 2015.

The team also placed the franchise tag on Jason Pierre-Paul. JPP is coming off his best season as a Giant since 2011 when he had 16.5 sacks. He finished 2014 on a hot streak, with nine sacks in his final five games to give him 12.5 on the season.

Damontre Moore returns for his third season and has the natural edge pass rush ability that coaches love. His two goals for his third year are becoming more consistent and stronger against the run.

Kerry Wynn came on at the end of his rookie year as well, tallying 1.5 sacks and an interception in the Giants final five games. An undrafted free agent out of Richmond last year, Wynn might have the opportunity to play a bigger role in 2015.

Robert Ayers signed as an unrestricted free agent with the Giants last offseason and made an immediate impact, totaling five sacks in his 12 games before tearing his pectoral muscle. An explosive force off the edge, Ayers will compete for a starting spot in 2015.

The Giants also have youngsters Jordan Stanton and Dominique Hamilton who will compete for roster spots.
