Chad Johnson is one of the most naturally talented wide receivers in football. He is a vertical threat. He runs good routes. He makes great catches. He is dangerous after the catch. When he is focused, he really can do it all. While the worst game of his career, Week 17 of 2009, is burned into the memories of Jets fans, there is only one team with Darrelle Revis.
It is worth noting that the three worst statistical seasons of his career were the past three campaigns. I would argue, however, that has a lot to do with his quarterback play. Carson Palmer was hurt for most of 2008 and mediocre in 2009 and 2010. I know the Bengals won the AFC North in 2009, but they leaned on a power run game that year. Only the Jets with a raw rookie quarterback had a higher ratio of runs to passes that season. Even with an erratic Palmer, Johnson went over 800 yards in the past two years. In 2010, he had to deal with Terrell Owens, Jermaine Gresham, and Jordan Shipley taking targets from him.
From what I have seen, Johnson still has something to provide.
