Brent Grimes has one of the most difficult challenges in the NFL. Week after week, the Miami Dolphins ask their No. 1 cornerback to trail a team's best receiver all over the field. Understandably, this job has its ups and downs—you win some, you lose some—but for Grimes in 2015, it's been much more down than up, much more losing than winning.
According to Pro Football Focus, Grimes has allowed 52 receptions on 78 passes thrown his way (66.7 percent) for 783 yards, five touchdowns, three interceptions and a 104.8 passer rating.
