It's always a given: Each and every offseason there are always some players that are a bit disgruntled about their contracts. There's no way around it.
Now why do we see so much of this in the NFL? Simple: There's not a lot of guaranteed money being thrown around like there is in Major League Baseball or other sporting leagues.
In that spirit, let's take a look at 20 NFL players who are most likely to complain about their contract next offseason.
With recent reports indicating that Percy Harvin is upset with his contract situation and reports that the Minnesota Vikings don't plan on trading the disgruntled player leads to believe that he will most definitely be upset entering next offseason—which is somewhat obvious, don't you think?
The tension has certainly already started this offseason and there's no doubt that it will carry over into 2013 if nothing is addressed.
This one depends on how well Mike Williams can continue to develop and produce in his third season in the NFL with the Tampa Bay Buccaneers.
Williams has caught 65 passes in each of his first two seasons while reeling in a total of 14 touchdown receptions. However, Williams is set to earn just $490,000 in 2012 and $575,000 in 2013.
There is a definite chance that Williams could look for more money in 2013, but that's just as long as he continues his development—but still, the Bucs are getting Williams' production for a complete bargain.
I find it hard to believe that the Panthers' Cam Newton would actually think about holding out but I do think there's a chance that he could ask for more money as he continues his progression as one of the NFL's elite quarterbacks.
Newton had a superb rookie season as he posted an 84.5 quarterback rating while accumulating 4,051 passing yards and scoring a combined 35 touchdowns.
Entering 2012, Newton is set to earn just over $1 million, just over $2 million in 2013 and then just over $3 million in 2014. As long as Newton continues to play well and proves to be a franchise quarterback, then he definitely has a case if he wants to earn some more money.
NaVorro Bowman of the San Francisco 49ers is a tackling machine but unfortunately for his sake, he's not being paid like one.
Bowman made just $490,000 in 2012 and will make just $575,000 in 2013 prior to his becoming a free agent in 2014. If Bowman continues to be as dominant as he was in 2011 when he racked up a massive 143 tackles, then he definitely has a very strong case if he wants to engage in contract negotiations.
Well isn't this a bit obvious?
Jets' cornerback Darrelle Revis held out back in 2010 for a brand-new four-year deal worth $46 million and now has recently complained about the deal.
Depending on what Revis does in a few weeks for training camp and if he holds out or not, there's a definite chance that he'll be complaining about his contract come this time next year.
I consider Redskins' Brian Orakpo to be an elite defensive player but he is far from being paid like one.
Orakpo has recorded at least nine sacks in each of his first three seasons in the NFL, but is still earning only $765,000 in 2012 and $1.61 million in 2013 prior to becoming a free agent.
If I were Orakpo, I would must definitely look for a pay-raise as he's playing like an elite pass-rusher while the Washington Redskins ultimately rip him off from his stellar play.
With Hakeem Nicks' five-year contract coming to an end in 2014, I could see the Super Bowl winning wide receiver complaining about his contract. He continues to prove that he is one of the NFL's elite wide receivers.
Nicks is earning just $750,000 in 2012 and $2.425 million in 2013 and then is set to become a free agent in 2014.
There's definitely a situation that I foresee happening if Nicks decides that he's worth more money and wants to gain some safety and sign a long-term deal with a large chunk of change. He could very well complain about his deal come next offseason.
We all know Jason Pierre-Paul is one of the NFL's elite pass-rushers. He racked up a stellar 16.5 sacks in the New York Giants' 2011 Super Bowl winning season.
Pierre-Paul might be an elite pass-rusher, but he's definitely not getting paid like one. J.P.P. will earn just $825,000 in 2012, $1.175 million in 2013 and $1.511 million in 2014.
If Pierre-Paul continues his dominance at harassing opposing quarterbacks, then he would have a very strong case if he decides to complain about his current contract.
Buffalo Bills' Fred Jackson might have just signed a brand new three-year contract back in May of this year as he's set to make $10.805 million—but the deal's only guaranteed money is his $3 million signing bonus.
Jackson has quietly played like an elite running back over the past few seasons as he's ran for a combined 2,923 yards in the last three seasons while scoring a combined 17 total touchdowns. If Jackson continues his production or even increases it, then I'm sure at the older age of 31 years old, he might look to reconsider his contract situation and seek more money.
I would be shocked to see the Aaron Hernandez actually hold out for a new contract, but I wouldn't be surprised if he asks for some more money considering his fellow teammate Rob Gronkowski just signed a whopping $55.23 million deal over eight years.
Hernandez is one of the most dangerous tight ends in the NFL today as he caught 79 balls for 910 yards and seven touchdowns in 2011, but he is set to earn just $575,000 in 2012 and $575,000 in 2013.
If you ask me, the New England Patriots are actually robbing Hernandez of some money—he's just that good and just that underpaid.
Kam Chancellor really came on strong for the Seattle Seahawks in 2011 as he played in 15 games and in all of those 15 games, he was all over the field as he finished with an incredible 97 tackles—which is impressive for a safety.
Chancellor is just 24 years old and is being paid only roughly half a million dollars in each of the next two seasons.
If I were the Seahawks, I would go to Chancellor before he comes and asks them for a pay raise. They should definitely lock this guy up if he proves to be the real deal yet again in 2012.
You might find the following hard to believe because Anquan Boldin is set to earn $6 million in each of the next two seasons with the Baltimore Ravens. Yet, he just doesn't rub off as the greatest guy, if you ask me—considering his contract dilemma back with the Arizona Cardinals in 2010 which prompted his trade to the Ravens.
With Boldin's deal winding down, I could see him looking for some long-term security, which could likely end up with him going to Baltimore's front-office and complaining about his contract.
However, what kind of case does he have? He has yet to catch more than 65 passes in a season, he has yet to record a single 1,000 yard receiving season and he has caught only 10 touchdowns in the last two seasons.
He's overrated and ripping Baltimore off—but then again, he is the kind of guy that would ask for a new contract.
With LaDanian Tomlinson officially retired, it's set in stone that Shonn Greene is the New York Jets' lead running back.
With that being said, Greene might be looking for some new money as he'll be carrying the entire workload for the Jets' rushing game.
Greene is only making $615,000 this season and then is set to become a free agent in 2013. If Greene wants to stay a Jet, then come mid-season this guy could be going to front office looking for a new deal—that if he produces at a high level, of course.
We saw the Giants' Victor Cruz emerge as one of the NFL's most explosive wide receivers a year ago, but there's just one problem: His track record is just one season of production.
Cruz is set to earn $540,000 in 2012 and then will be a restricted free agent in 2013. If Cruz doesn't get the money that he wants following this season or is even franchise tagged, then we could very well see a situation develop much like the current one with Mike Wallace and the Pittsburgh Steelers.
Ryan Mathews is pretty underpaid for being a team's primary ball-carrier.
From now until 2015 when Mathews becomes a free agent, he will not earn more than $1.47 million in each of those seasons—in fact, he's only made $712,750 in 2012 so far.
If Mathews can develop and prove that he can be a workhorse and an elite running back for the San Diego Chargers, then he's a guy that I could see complaining about his deal in 2013.
The 24-year-old Geno Atkins is something special because he recorded 7.5 sacks in his second season with the Cincinnati Bengals in 2011 to go along with 47 tackles.
Atkins is not only a great interior run-stopper but also a dominant pass-rusher. However, he's not getting paid like one.
Atkins is living off of his rookie contract that's set to pay him $490,000 in 2012 and $575,000 in 2013.
There's no doubt in my mind that this guy needs to be paid a tad bit more money—he's just that dominant.
When healthy, Jeremy Maclin is one of the best No. 2 wide receivers in the NFL and could most certainly be another team's primary option if he wasn't in Philadelphia.
In 2011 for the Philadelphia Eagles, Maclin reeled in 63 receptions for 859 yards and five touchdowns, despite missing three games.
Maclin will earn just $993,250 in 2012 and a little over $2.5 million in 2013. Granted, $2.5 million is much better than $993,250, but there is a chance that he'll feel that he's worth much more than the money he's already getting from Philly.
The Packers' Jordy Nelson might run a limited route tree, but for what he does, he does it at a very high level and is one of the NFL's more explosive wide receivers.
Nelson is making just $1 million this season and will make $2.7 million in 2013 and $2.55 million in 2014, prior to becoming a free agent.
Granted, Nelson is making good money, but if he continues to catch 65-plus balls for 1,200-plus yards and 10-plus touchdowns then he definitely deserves a little bit more money for his production.
I really don't think Andy Dalton would actually hold out, but I could see him asking for more money as he continues to prove to the Cincinnati Bengals that he's the team's quarterback future and the team's franchise player.
Dalton will make less than a million in each of the next three seasons until his contract is up in 2015.
If you ask me, Dalton is worth a lot more money than the Bengals are giving him and I wouldn't be too surprised if they actually go to him and offer him a massive extension to make him one of the highest paid quarterbacks in the NFL.
Vontae Davis is one of the best young cornerbacks that the NFL has to offer, but he's just not getting paid a sum equivalent to his production with the Miami Dolphins.
Granted, it's just his rookie deal, but Davis is only earning $957,000 in 2012, $1.136 million in 2013 and then will be a free agent in 2014.
Davis is a very special cornerback who continues to prove to be a reliable option in the secondary. He could certainly go to Miami's management and ask for a new contract extension, considering the work that he's put in with the Dolphins.
