This is the hardest receiver in the NFL to cover, according to Dolphins CB Brent Grimes

He would know.

Eight-year NFL veteran Brent Grimes has seen his fair share of wide receivers.

Typically matched up against the opposition's best player, Grimes was recently asked who the toughest receiver in the NFL to defend is, and his answer shouldn't shock anyone, via ESPN:

"I would say Calvin Johnson because of size. He's huge. He's like an NBA small forward playing NFL receiver, and he still has the ability to run routes. But there's a few of them that's really good. I like Julio [Jones] a lot. But Calvin Johnson is just huge, and that combined with his athletic ability presents a lot of problems."

Johnson has recorded over 1,000 yards receiving in each of the last five seasons, including 2012, where he nearly eclipsed 2,000 yards through the air. The 6'5", 239-pound Johnson is a five-time Pro Bowler and arguably the best pass-catcher in the league.
