Chad (Ochocinco) Johnson
Maybe it wasn't the right time to get overly excited about a 33-year-old receiver, but when Chad Ochocinco was traded to the Patriots for a 2012 fifth-rounder and 2013 sixth-round pick in 2011, there was hope he would be the exact receiver the Patriots were looking for post-Randy Moss era to join Wes Welker and Deion Branch.
He was coming off another productive season with the Bengals, the team he spent the entirety of his career with, but he looked like a completely different player once arriving in New England.
Although he wasn't given a starting role, Johnson had the least productive season of his career, totaling just 15 receptions for 276 yards and one touchdown, all during a season that saw Tom Brady thriving, the rise of the double tight ends in Rob Gronkowski and Aaron Hernandez and a Super Bowl appearance.
Because he wasn't the contributor they anticipated he would be, Johnson was released at the end of the season, essentially ending his NFL career.
