Many consider cornerback to be the hardest position to play in football. You have to be the BEST athlete on the field, since you’re having to run stride-for-stride with the best athletes on offense, while operating in the disadvantage of not knowing where they’re going.
Corners are rarely seen making good plays on TV cameras, instead mostly only being highlighted when they got beat. It’s a thankless job that requires outstanding athleticism, nearly inhuman reaction time, and a whole lot of pre-play studying. Oh, and on top of that, you also have to break up passes and make tackles while complying with rules around touching the receiver that get tighter every year.
