For two years, the Packers tried to turn Randall from the safety he was at Arizona State into an outside cover man in the NFL. But it was in an offseason review of their defense that Capers, cornerbacks Joe Whitt and coach Mike McCarthy decided to move Randall inside into the role – the "star" – similar to the one previously played by the likes of Micah Hyde and Charles Woodson.

“It’s a lot of what he did in college, first off,” Whitt said last week during the Packers’ minicamp. “He’s comfortable being inside, he has good quickness, he has good instincts, he has the ability to see and catch the flash of the football, he’s a smart player. I think he’s becoming a better communicator on the field and so he has the ability to be successful inside there.”
It might be seen as a disappointment that a 1st round pick will only be a slot corner. But at this point, who cares? If he can be an effective slot corner, he'll make the defense better. The trio of House Gunter and King should be able to hold down the outside positions, enabling Randall to stay inside for the most part.
