Every year there is a certain level of turnover that exists on each team's NFL roster.
The Kansas City Chiefs have seen a great deal of turnover on their roster after going through three different head coaches and many assistant coaches in the last four years.
Here are my predictions for the Chiefs players who will not be back for the '12 NFL season.
Last offseason, Chiefs GM Scott Pioli decided to take a flier on then-free agent safety Sabby Piscitelli.
It turned out to be a bad decision by the Chiefs.
In his first season with Kansas City in 2011, he was repeatedly burned in coverage and struggled with tackling as well.
With star safety Eric Berry likely to make his return next season, Piscitelli is as good as gone.
Urban was signed by KC back in the '10 offseason due to his previous Arizona connection with former Chiefs head coach Todd Haley.
Since then, he has managed to contribute just four receptions for 35 yards and a touchdown.
With the amount of talent in the current Chiefs receiving corps, it's hard to see where Urban fits on the roster for next season and beyond.
It seems that he has already played his last down as a member of this organization.
Anthony Toribio has done nothing in his time with the Chiefs to warrant another season with this team.
In his first year with the team, he collected just three tackles in five games, and he didn't even register a tackle last season.
It's hard to imagine how a player can continue to play for the same team when he doesn't play a down and is not on the practice squad.
Toribio will likely be looking for a new home later this offseason.
Veteran DT Kelly Gregg was brought in last season to serve as a stop-gap player at that position.
Even though he showed flashes of greatness at times throughout the season, he clearly displayed why the Ravens gave up on him and why his days as an NFL starter are likely over.
KC is already grooming second-year man Jerrell Powe to play defensive tackle, and they might take a DT in the higher rounds of April's NFL draft as well.
After playing a year for the organization, it's time for Gregg to move on from the Chiefs.
There's no question that Chiefs center Casey Wiegmann has been one of the most durable players at his position in NFL history.
He hasn't missed a snap since the '01 season and has been the measure of consistency for all NFL centers during his time in the league.
However, the former University of Iowa star has been contemplating retirement for the past two years and, at 38 years old, it might be time for him to finally call it a career this offseason.
After 16 seasons and 227 games played, we might have seen the last of Casey Wiegmann—not only as a Kansas City Chief, but also in the NFL as well.
The writing has been on the wall for veteran RB Thomas Jones.
Last season, he rushed for just 478 yards and had a 3.1 YPC average for KC's rushing attack.
At 33 years old, he doesn't have the speed or power that he used to run with back in his younger days.
With Jones becoming a free agent this offseason, don't expect him to be back in Kansas City next season.
It's still a mystery how safety Reshard Langford made the Chiefs roster last season in the first place.
Like many of his other secondary teammates, he failed to fill the shoes of injured safety Eric Berry by getting beat in coverage many times, including in this touchdown pass against the Denver Broncos in the photo above.
With Berry, Kendrick Lewis and veteran Jon McGraw, Langford doesn't have a place on this roster anymore.
His time with KC should run out later this offseason.
Veteran tight end Anthony Becht was signed before the beginning of the '11 season mainly for insurance purposes after starting TE Tony Moeaki was lost for the year with an ACL injury.
In nine games with the Chiefs, he caught just three passes for 26 yards.
With Moeaki coming back next season and veteran Leonard Pope likely to back him up once again, Becht's chances of making the team suddenly become very slim.
Since he will be 35 years old next fall, I don't see KC retaining this former first-round pick for another season in 2012.
Orton was picked up toward the end of last season via waivers from the Denver Broncos.
He was able to put together an impressive 2-1 record as the starting QB for KC, but all signs point to him not coming back to the Chiefs in 2012.
Luckily for Orton, there will be several other NFL teams that could use his services as their starting quarterback for next season and beyond.
KC claimed Maneri off waivers before the start of the '11 NFL season.
It's still unclear why the Chiefs signed him in the first place, as he barely saw the field last season.
The ex-Patriot played in just six games and made one start while primarily being used as an extra blocker in certain situations on offense.
I see no reason why Kansas City will bring him back next season.
