The New York Giants defensive line is a well-respected one around the league. Led by six-year pro Justin Tuck, the G-Men ranked fifth in the league in sacks last season, and third in yards lost on sacks.
While Osi Umenyiora is a major piece of that defensive line, he is replaceable.
Mathias Kiwanuka has played his fair share of linebacker for the Big Blue, but has the ability to step back into his natural defensive end position if Umenyiora is not retained.
If Kiwanuka is needed at linebacker, 2010 first-round pick Jason Pierre-Paul is capable of stepping up to take the spot of Osi.
Bottom line, the Giants' defense can survive without Osi, and would still have an above-average defensive line if he were to leave.
Defensive line without Osi Umenyiora:
Left End - Justin Tuck
Left Tackle - Barry Cofield
Right Tackle - Chris Canty
Right End - Mathias Kiwanuka, Jason Pierre-Paul
