Osi Umenyiora Rips Jerry Reese, New York Giants GM, In Email To Newspaper

Just like last year, Osi Umenyiora and the New York Giants are having a tough time negotiating his contract. And just like last year, the star defensive end vented his frustration in an email. In a letter sent to the New York Daily News, Umenyiora lashed out at Giants general manager Jerry Reese claiming that he is trying to make him look "like a greedy pig."

The email was sent one day after Reese told ESPNNewYork that the team has offered Umenyiora -- who is entering the last season of the seven-year deal he signed in 2005 -- an extension for two straight years.

"Last year I was offered incentives. This year they offered me in guaranteed money, HALF of what they just gave Kiwi guaranteed. HALF," Umenyiora wrote in Sunday's email. "I'm not making that up. Then Jerry tells the world they offered me an extension and I turned it down. And I look like a greedy pig for turning it down. Hilarious."

Mathias Kiwanuka, who had a career-high 84 tackles last season, recently signed a three-year contract extension worth $21.75 million.

Hours before the 2012 NFL Draft began, Umenyiora hinted at a possible holdout and even went as far as to urge the Giants to trade him during the draft if they don't give him an extension. The Giants did not trade the eight-year veteran, which as ESPN's Adam Schefter pointed out on Monday, may have been their best opportunity to deal him.

Last Summer, Umenyiora sent an email to the Associated Press saying that he was annoyed with being criticized and portrayed as a bad guy for asking the team to renegotiate his contract.

Umenyiora, 30, recorded nine sacks, 25 solo tackles and two forced fumbles in 2011.
