took the field as a corner. It takes time to get to college speed. And it generally takes longer for corners and more especially safeties, who are having to somewhat guess where to go on a given play, vs a WR who knows his route. It's even harder in a defense that requires their DBs to be on islands, like Utah's does.

You're drunk on the wrong kool aid if you think any team can simply reload 8 of 8 DBs and not experience issues early on.
