"DeAngelo Williams says he's not "upset or aggravated or anything like that" about the Carolina Panthers allowing him to enter the final year of his contract without a lucrative extension despite two stellar seasons.

"I'm in no shape, form or fashion upset with anybody because I haven't gotten a new deal," Williams said after a morning practice Tuesday, the second day of the Panthers' organized team activities. "I just know at the end of this fifth year, somebody's got to make some decisions."

Williams, a 2006 first-round draft pick, has rushed for 2,632 yards and scored 27 touchdowns the past two seasons, emerging as one of the NFL's elite running backs.

He is one of several young stars the Panthers have said they want to keep long-term - including linebackers Jon Beason and Thomas Davis, and center Ryan Kalil - but to whom they haven't given contract extensions.

General manager Marty Hurney said last month that new rules related to the collective bargaining agreement stalemate make it difficult to sign players with years remaining on their contracts to extensions, because the deals would have to include enormous signing bonuses."
