25. Nnamdi Asomugha, Philadelphia Eagles (2011):

Asomugha was considered a true shutdown corner whom teams rarely chose to throw at during his early-career years in Oakland. After making the Pro Bowl three straight years, the Eagles lavished five years and $60 million with at least $25 million guaranteed on him in their infamous 2011 sending spree.

It did not pay off, as Asomugha was anything but the shutdown defender everyone had come to fear him as in Oakland. He was repeatedly beaten, and the Eagles did not make the postseason in either of his two years with the team. After not agreeing to a restructured contract before the 2013 season, he was released by the Eagles. He played half of one more season in San Francisco.
