Patrick Peterson's always has been an overachiever. A star defensive back at Louisiana State University, he was drafted fifth overall by the Arizona Cardinals in 2011. And he started fast in the National Football League: In his first season in Glendale, Peterson, a cornerback/returner, ran back four punts for touchdowns. On top of that, at only 24, he's been named to the Pro Bowl twice as a cornerback. His defensive play's been spectacular, naturally, with 12 touchdowns and 162 tackles. And he's been able to avoid serious injury, never missing a game in two years. Now he's getting the big money, an extension of his current rookie contract worth $70 million over five years, $48 million of which is guaranteed. This puts him in a league of his own at his position. With these numbers, Peterson will be the highest-paid cornerback in the NFL, eclipsing even defending Super Bowl champion Seattle Seahawks corner Richard Sherman. Sherman got a four-year, $56 million deal. When Sherman signed his lucrative agreement after last season, he and Peterson engaged in a war of words over who was the best cornerback in the league. It continued after news of Peterson's deal leaked out. When Peterson tweeted to Sherman: "Yu mad bro LMAO" followed by a bunch of smiley faces, Sherm tweeted back a picture of his hand laden with a Super Bowl ring. Which begs the question: Can the Cardinals overcome arguably the two best teams in the NFL, Sherman's 'Hawks and the San Francisco 49ers, and get Pat a ring of his own?
