A former second-round pick out of Western Michigan, Greg Jennings has been a staple in Green Bay's passing game alongside longtime veteran Donald Driver and fellow receivers James Jones and Jordy Nelson, and became the team's No. 1 receiver on the oustide with his smooth route running and deep threat ability.

But lately, Jennings has stated that he's beginning to see the 'writing on the wall' when it comes to his future in Green Bay. Jennings becomes an unrestricted free agent at the end of the season, and has made little progress in terms of a contract extension. And after struggling through the season with groin and abdominal injuries, which forced him to miss a decent part of the season, it's getting harder to see Jennings returning back to Lambeau in 2013.

And while Jennings was down, the other receivers shined. Fellow receiver James Jones is having a career season, nabbing 12 touchdown receptions with 622 receiving yards. Once thought of as trade bait on several occasions, the Packers have stayed committed to Jones and he has pulled through. Jordy Nelson, who has essentially become the primary receiving threat in this offense, has continued his ascension among the receiving corps, and has 658 receiving yards and six touchdowns despite his nagging hamstring injury. But the biggest jump has come from the second year-man out of Kentucky by the name of Randall Cobb. Having played primarily on special teams as a returner his rookie year in 2011, head coach Mike McCarthy worked to get Cobb more involved in the offense in 2012. And after having 892 receiving yards to lead the team and seven touchdowns later, Cobb has quickly become a dangerous weapon in the Packers' passing attack.

And even when Jennings returned, it feels as though he hasn't, as Nelson, Cobb, and Jones have become the three-headed receiving options for quarterback Aaron Rodgers. And at age 29, Jennings is still considered in the prime of his career, and still has enough left to have plenty of demand in free agency. But what are some possible landing spots for the seven-year veteran?

1. New York Jets

A team in need of upgrades at receiver to complement Santonio Holmes on the outside, the Jets are already in the market for a quarterback. And whether they address their quarterback situation in free agency or early in the NFL Draft, it would help that quarterback tremendously to have a smooth, route running deep threat like Jennings to go along with Holmes and Jeremy Kerley, who functions best out of the slot.

2. Miami Dolphins

The Dolphins have already began putting their effort towards developing rookie quarterback Ryan Tannehill. And he has shown flashes and plenty of potential. But the next step involves putting the right pieces around him. And Jennings could become one of those pieces for a questionable receiving corps that needs to help out Brian Hartline and aid in Tannehill's progression.

3. St. Louis Rams

The Rams took a big gamble by selecting receiver Chris Givens out of Wake Forest, and while he has come on as of late, the Rams have a young receiving corps that could use a guy like Jennings in its ranks. Danny Amendola can't always stay healthy long enough after he makes a big play and would function even better with the help of a receiver like Jennings. This way, the Rams could add more to their passing game and focus on improving their offensive line.

4. Minnesota Vikings

It seems customary that the Vikings end up signing Packers players. Recent examples included safety Darren Sharper, kicker Ryan Longwell, and quarterback Brett Favre. With receiver Jerome Simpson only signed for a year and not making the impact they expected, and Percy Harvin questionable to re-sign an extension with the team, the Vikings will need a viable receiving threat to keep defenses honest and from stacking the box against running back Adrian Peterson. Here, Jennings would not only be going to a young team that can contend, but he would become a No. 1 receiver if Harvin departs, or start on the outside and allow the Vikings to do more with the versatile Harvin on offense and special teams.

Jennings is still a very capable receiver and is one of the best at his position when healthy, and should the Packers let him walk, he can shine in another uniform and bring plenty of professionalism for another franchise.
