In Week 17, numerous NFL players showcased the reasons they will be changing jerseys before the start of next season.
Not all of these players faltered in the regular season finale, but the vast majority bumbled and stumbled their way to the finish line.
Which players proved that change is imminent?
Let's examine five stars (well, four stars and Mark Sanchez) that played their way out of town in Week 17.
The writing has been on the wall in Philadelphia for most of the year.
Head coach Andy Reid is likely on his way out of town, and Michael Vick will be following him out the door. Whether the Nick Foles era is truly about to begin or if the Eagles will explore other options is irrelevant; Vick's future is elsewhere.
His Week 17 performance was a microcosm of the entire 2012 campaign.
Vick was not terrible alone, but the Eagles as a whole were a dysfunctional mess, losing 42-7 to the divisional rival New York Giants and failing to show any desire or passion.
There was a play in the middle of the Detroit Lions' Week 17 matchup with the Chicago Bears that showcased the shortcomings of Kyle Vanden Bosch.
After the defensive line caused a great deal of pressure, Jay Cutler fumbled the ball. KVB had a chance to pick it up and yet bobbled the ball, allowing Chicago to recover.
This was the type of play that he used to make, but KVB's game is slipping. He does not wreak havoc off the edge like he used to; in fact, he has just 3.5 sacks all season (zero in the last 10 games.)
Perhaps it is time for the 34-year-old defensive end to accept retirement.
The New York Jets organization has to have seen enough by now, right?
Quarterback Mark Sanchez is the same inaccurate mess that was drafted in 2009. Sanchez has the lowest completion percentage of any starting quarterback in the league. He has just 13 touchdowns compared to 17 interceptions this season.
Week 17 was just the icing on a cake that has been stale since the beginning. After inexplicably turning back to Sanchez once Greg McElroy was injured, Sanchez rewarded the Jets with just 205 yards passing, zero touchdowns and an interception that was returned for a touchdown.
It would be shocking to see Sanchez in New York next season.
While Greg Jennings was sidelined with injury for a large part of the 2012 season, the Green Bay Packers offense proved that it can survive and thrive without him.
He is non-essential to the Packers, but the soon-to-be free agent proved his value to potential suitors in Week 17.
Jennings caught eight passes for 120 yards and two touchdowns. A fully healthy Jennings will be one of the best free agents on the market, and at only 29 years old, Jennings should have plenty of tread left on the tires.
There were questions about his health heading into Week 17, but those have been resoundingly answered.
1-for-1 passing for six yards.
That was Alex Smith's stat line in Week 17, and it nicely explains the reason that he will likely not be back with the San Francisco 49ers next season.
Head coach Jim Harbaugh has decided that Colin Kaepernick is his starting quarterback moving forward. Right or wrong, that is the new direction of the 49ers, and Smith does not fit into the equation.
He was playing great before his concussion and will undoubtedly be a popular piece of trade bait this offseason.
