As evidence by every NFL season, there are a few undrafted free agents who make some noise. Receiver Doug Baldwin from Seattle perhaps made the biggest splash, as he was the Seahawks' main target.
In addition, two undrafted free agents from 2011 will be playing in Super Bowl XLVI for the New York Giants; full back Henry Hynoski and linebacker Mark Herzlich.
And finally, New Orleans Saints safety Isa Abdul-Quddus from Fordham led the Big Easy in forcing five fumbles. That said, here are some potential undrafted free agents to keep an eye on this offseason.
Frank Alexander: DE, Oklahoma
Not very strong or quick by any means, but has the ability to control the edge. Alexander recorded 15.5 sacks between the last two seasons along with 32 tackles for loss.
In 2011, he forced three fumbles collected 54 tackles and defended nine passes. His lack of athleticism will hurt in the pros as well as his slightly small size for a defensive end.
Therefore, if Alexander gets picked up, expect it to be by a 3-4 front team. His pass rushing skill will suit well off the edge and he is capable of improving against the pass. Let's face it, you don't deflect nine passes without having an idea of when and where the ball is being released.
As long as Alexander keeps getting quicker and the instincts high, he'll make for talented depth at the very least.
Jarrett Lee: QB, LSU
As if there is any evidence as to why the LSU Tigers lost the National Championship, it's because they didn't know how to approach a quarterback controversy. In the long run, it proved to be the catalyst that killed their confidence.
Before the Alabama game in the regular season, Jarrett Lee had thrown 13 touchdowns to just one pick. And then the one time he gets exposed, head coach Les Miles makes a change to Jordan Jefferson.
Although the Tigers won the battle, they lost the war as 'Bama avenged in the BCS title game. Had Lee been given another opportunity, he would have improved because his performance when stepping in at the beginning of the year was impressive.
In the NFL, Lee is your prototypical game-managing QB who can be effective enough to win. He rarely makes mistakes and always takes what the defense gives him. After all, that's much better than a guy who thrives solely from scrambling and not being able to read defenses.
Lee at least has that potential.
Jarrett Boykin: WR, Virginia Tech
Jarrett Boykin's 6'2", 218-pound frame is what will get him a look into the NFL if anything. He was part of an offense not predicated so much on explosiveness as it was methodically moving the chains with a dual-threat quarterback.
Still, Boykin compiled an average of 814 receiving yards each of his last three seasons, while racking up 18 career touchdowns. Between his final two years, Boykin caught 114 passes and averaged over 14 yards per catch.
The great thing is that he is a possession target but strong enough to get separation from smaller defensive backs and equally as big linebackers.
A lot of what Boykin does downfield is simply get first-downs. He is a big target over the middle and is a reliable fade route receiver inside the red-zone. Provided that he can get quicker off the snap his whole game will change for the better.
