4. DE/OLB Mathias Kiwanuka
Career with Giants: 2006-2014, 82 games started, fifth most tackles for loss in team history, third most QB hits in team history, two-time Super Bowl champion
Just like Oates, it seems like Kiwanuka is often forgotten amongst all the talent he played alongside. Unlike Oates, Kiwanuka played on an incredibly talented defensive line that featured names like Justin Tuck, Jason Pierre-Paul, Michael Strahan, Osi Umenyiora, and more. Despite this, Kiwanuka still managed to stand out and be a valuable player in both the Giants' 2000s Super Bowl victories.
Over the course of his nine-year Giants career, Kiwanuka racked up 412 combined tackles, 38.5 sacks, 69 tackles for loss, and 13 forced fumbles. These are incredibly respectable numbers for someone you hardly hear brought up by New York fans, let alone NFL fans in general.
While Kiwanuka would miss the team's first Super Bowl victory with injury, he was a very valuable player in their second championship run in 2011-2012. He provided a consistent presence on a defense littered with noteworthy names. Not everyone will remember Kiwanuka's stability as a player, but he will always be remembered by the realest Giants fans.
