Arguably, 2009's biggest breakout stars were Chris Johnson and Darrelle Revis.
The numbers speak for themselves.
Johnson exploded onto the scene in his second season in the NFL, winning Offensive Player of the Year. He racked up 2,500 total yards and 16 total touchdowns.
Revis broke out in his third season, becoming the league's best corner in many people's eyes. The list of receivers he shut down was certainly impressive, including the likes of Andre Johnson, Reggie Wayne, and Randy Moss.
Revis held the opposing top receivers to 290 total yards on the season, compared to their combined averages of 830 yards.
Certainly impressive campaigns by each, but the reason we are talking about the two today is obvious: Both have been in the headlines this offseason for complaining about being grossly underpaid.
On the basis of last season, you probably agree that each should be paid more.
But here comes the age-old question: Once they have their money, will they have the drive to build on last season's campaign?
The key to being a star in the NFL is a stretch of great production, not just one season.
Both of these guys are young, so they have the capability to continue to grow.
But it is surely a difficult task to build on such a stellar 2009 for this pair.
Can Johnson really improve on his 2,500 total yards? Or is the better question, can he duplicate that success?
Will Revis be able to shut down every opponent that comes his way again?
If they don't, will they be seen as a disappointment? Or, dare I say, a one-year wonder?
Surely, the target will be on each of their backs. The rest of the NFL has heard enough about the greatness of these two. Now is their chance to make a name for themselves by taking it to Revis or Johnson.
The motivation of trying to score a new contract drives a lot of players. You have seen players explode time and time again in "contract seasons." In the NFL, you may argue, that every season is a contract season because you may be cut if you do not produce.
So, that point may be moot to many of you. The motivation may be in having that target on their backs, or in trying to become one of the great ones. This season may be the chance for each to prove that he has that drive.
Having a breakout season is one thing, but turning it into the norm is a tough battle that these two will be facing this season.
With all the talk about not being paid enough, they both have to respond with seasons comparable to 2009, otherwise the doubts will start flowing.
The advantage Revis has is that the Jets have added even more pieces around him to help him out. So, he might have an even better 2009. But Revis is still holding out, and the longer he holds out, the less prepared he will be for 2010.
Odds say that they will not be able to repeat those fantastic seasons, but would that make them a flop?
Or, are the two already among the NFL's best? Was 2009 the beginning of their path to NFL stardom, and will 2010 cement their status as certifiable stars?
