While Adderall may have helped Joe Haden when he attended classes at the University of Florida, his use of the banned stimulant and subsequent four-game suspension is taking its toll on the Cleveland Browns defense.
Commissioner Roger Goodell and Haden shared some laughs in 2010 after the Browns announced that Haden would be the seventh overall pick, but nobody's laughing now.
It was evident that the Browns felt Haden's absence on defense last week as they allowed Andy Dalton to tie a career high and throw three touchdowns in the Bengals' 34-27 win.
It doesn't get better as the 0-2 Browns play three more games before their superstar cornerback returns.
The Browns will be Haden-less when they face Ryan Fitzpatrick, Joe Flacco and Eli Manning.
Let's take a closer look at how Haden's suspension affects the team's defense.
