Although Brett Favre did begin his career with the Atlanta Falcons, he turned in a Hall of Fame career with the Green Bay Packers.

He won three consecutive MVP awards and broke the career record in virtually every passing statistic, including completions, attempts, passing yards, touchdowns, consecutive games played, and yes, interceptions.

But then he became the player who cried retirement at the end of his career, playing a mediocre year with the New York Jets and an extremely successful season with the Minnesota Vikings.

Couldn't he just have retired with the Green Bay Packers? 

Originally cut by the Pittsburgh Steelers in 1955, Johnny Unitas played 17 incredible seasons with the Baltimore Colts.

He earned the NFL's Most Valuable Player award three times and threw for a touchdown in a record 47 straight games. He was basically the inventor of the two-minute drill and led the Colts to an overtime victory in the 1958 NFL championship game.

Let's just pretend that he never played for the San Diego Chargers in 1974.

Montana is arguably the greatest quarterback to ever live and he proved it during an illustrious NFL career with the San Francisco 49ers.

He led the Niners to four Super Bowl titles, winning the game's MVP award three times. He also earned consecutive MVP awards in 1989 and 1990.

But he lost a classic quarterback controversy with Steve Young and headed to the Kansas City Chiefs for the final two seasons of his career. He did lead the Chiefs to an AFC championship game berth but it wasn't the ideal lasting memory.

McNabb was drafted with the second overall pick in the 1999 draft and turned in a great career in Philly, earning six Pro Bowl selections and leading the team to the NFC championship game five times, including a berth in Super Bowl XXXIX.

But he was traded to the Washington Redskins after the 2009 season and had a dismal season in the nation's capital. Who knows where he'll be next year? It's really a shame.

McNair played 13 seasons with the Houston Oilers/Tennessee Titans, earning a trio of Pro Bowl selections and a tie for the 2003 Most Valuable Player award.

In the 1999 season, he led the Titans to the Super Bowl, where they overcame a 16-point second half deficit and came within a single yard of tying the game on the final play.

He played for the Baltimore Ravens in 2006 and 2007 before retiring. 

Arguably the most athletic quarterback in NFL history, Randall Cunningham was a threat as both as a passer and a runner.

He earned the Bert Bell Award as the NFL Player of the Year twice with the Philadelphia Eagles (1988, 1990), and once with the Minnesota Vikings (1998).

It's a shame that he had to spend his final two seasons with the Dallas Cowboys and Baltimore Ravens. 

Namath played 12 seasons with the New York Jets, famously guaranteeing a victory (and then delivering) over the powerful Baltimore Colts in Super Bowl III.

But he played for the Los Angeles Rams in the 1977 season, starting just four games.

Emmitt Smith played 13 seasons with the Dallas Cowboys, winning four league rushing titles and setting a single-season record of 25 touchdowns in 1995. He also earned a league MVP award and helped the Cowboys win three Super Bowls in four seasons.

After breaking Walter Payton's all-time rushing record in the 2002 season, Smith was released by the Dallas Cowboys after the season.

He joined the Arizona Cardinals where he finished out his career after the 2004 season. 

During his nine seasons in San Diego, Tomlinson won two NFL rushing titles and won the MVP award in 2006, when he rushed for a league record 31 touchdowns.

He joined the Jets in 2010 and actually had a productive season. But he doesn't seem to have more than a year or two left. It would have been nice if he had stayed in San Diego to finish out his career. 

During his 12-year NFL career, Dorsett rushed for 12739 yards and played for a Super Bowl champion. He holds the NFL record for longest rushing touchdown (99 yards), which was set in the 1982 season.

He rushed for 703 yards and five touchdowns in 1988 with the Denver Broncos before retiring and earning a berth in the Hall of Fame. 

Harris caught the Immaculate Reception and was a key member of four Super Bowl champion Pittsburgh Steelers teams. He earned Super Bowl MVP honors against the Minnesota Vikings in Super Bowl XL.

After a successful 12-year stint with the Steelers, he joined the Seattle Seahawks and rushed 68 times for just 170 yards and no touchdowns before retiring.

Even though he made just a single Pro Bowl, Taylor had a successful 11-year stint with the Jacksonville Jaguars.

He joined the New England Patriots after the 2008 season but has made very little contributions in the past two seasons, rushing 106 times for 424 yards and four touchdowns.

OJ had one of the top peaks for any running back in history, leading the league in rushing four times in a five-year span.

He became the first player to top 2000 yards in a season, rushing for 2003 yards in 1973. Two years later, he scored 23 touchdowns.

He was traded to the San Francisco 49ers for a second round draft pick after the 1977 season and scored just four touchdowns in his final two seasons. 

Alexander had an extremely productive eight-year stint with the Seattle Seahawks. In 2005, earned MVP honors when he led the league with 1880 rushing yards and scored 28 total touchdowns, a new league record.

He joined the Washington Redskins for the 2010 season, where he played in four games and rushed for a pathetic 24 yards on 11 carries. 

Campbell was a stud during his six and a half seasons in Houston. He was named the NFL Offensive Player of the Year in each of his first three seasons, winning the NFL Most Valuable Player award in 1979.

The greatest power back in league history was traded to the New Orleans Saints in the middle of the 1984 season and rushed for one touchdown during his 24 games with the Saints.

Taylor turned in a Hall of Fame career with the Green Bay Packers, winning the league's MVP award during the 1962 season. He led the Pack to championships in 1961, 1962, 1965 and 1966.

But in 1967, he joined the New Orleans Saints and rushed for 390 yards and one touchdown before retiring.

Craig played eight years with the San Francisco 49ers, leading them to Super Bowl titles in 1984, 1988, and 1989. He became the first player in league history to top 1000 yards rushing and receiving in the same season (1985).

The four-time Pro Bowler rushed for just 1225 yards and six touchdowns in the final three seasons of his career, one with the Raiders and two with the Vikings.

The 1996 Offensive Rookie of the Year, Eddie George earned four Pro Bowl selections during his eight seasons with the Houston Oilers/Tennessee Titans.

He was just the second running back in league history to rush for 10,000 yards without ever missing a start (joining Cleveland's Jim Brown).

He signed a one-year contract with the Dallas Cowboys before the 2004 season, rushing for 432 yards and four touchdowns before retiring.  

Thurman Thomas was as valuable as Jim Kelly to the four-time AFC champion Buffalo Bills in the 1990s.

He led the league in yards from scrimmage four straight times and was selected as the Most Valuable Player after the 1991 season.

But he spent an awkward year with the Miami Dolphins in 2000, retiring after rushing for 136 yards and no touchdowns. 

One of the most underrated players at any position in NFL history, Motley averaged 5.7 yards per carry during his eight seasons as fullback for the Cleveland Browns. 

But he joined the Pittsburgh Steelers for the 1954 season, where he carried the ball twice. There aren't even any pictures of Motley playing for the Steelers. 

The NFL's career leader in receptions, receiving yards, and touchdowns, Rice earned three Super Bowl rings with the San Francisco 49ers.

He retired with the single-season record for receiving yards (1848 in 1995) and receiving touchdowns (22 in just 12 games in 1987).

His stint with the Oakland Raiders worked out because he was still productive. But why did he need to join the Seattle Seahawks and later try out with the Denver Broncos?

The second leading receiver in NFL history, Bruce was a four-time Pro Bowler with the Rams.

He helped the Greatest Show On Turf win the Super Bowl after the 1999 season, catching a game-winning 73-yard touchdown pass from Kurt Warner with just under two minutes remaining.

His final two seasons, both spent with the San Francisco 49ers, fall under the forgettable category. 

With the Buffalo Bills, Andre earned seven straight Pro Bowl selections and led the team to four consecutive Super Bowl (losses). 

He topped 1000 yards four times and was rarely injured.

And with the Washington Redskins in 2000, well, he had 103 receiving yards. 

Monk was underrated yet dominant with the Washington Redskins, leading the team to three Super Bowl titles with three different starting quarterbacks.

His big season was a 106-catch, 1372-yard output in 1984.

He caught 46 passes with the Jets in 1994 and just six with the Eagles in 1995. 

Holt was an explosive receiver, and one of the main components of the Greatest Show On Turf for the St. Louis Rams a decade ago. He led the NFL with 1635 receiving yards in 2000 and 117 catches and 1696 yards in 2003. 

He had a fairly decent season with the Jaguars in 2009 (722 receiving yards) but it was much more fun watching him catch passes from Kurt Warner and Marc Bulger than David Garrard. 

Carmichael is one of the most underrated wide receivers in NFL history. He earned four Pro Bowl selections, including a 67-catch, 1116-yard, nine-touchdown performance in 1973.

In 1980, he led the Eagles to the Super Bowl.

He joined the Cowboys in 1984 and caught just a single pass for seven yards.

With the Kansas City Chiefs, Tony Gonzalez has established himself as arguably the greatest tight end in NFL history. He made ten consecutive Pro Bowl selections and led the entire NFL with 102 receptions in 2004--an unprecedented feat for a tight end. 

Since joining the Atlanta Falcons, well, he's actually been pretty productive still, even earning a Pro Bowl selection this past season at age 34. But it's not just the same watching him play in the wrong team's red uniform.
