The 18th overall pick and first-ever selection for new Packers GM Brian Gutekunst in this year's NFL Draft after multiple trades jockeying for position, Alexander came to Green Bay with a reputation of unbridled confidence and he's lived up to it through his first season with the Packers.

"How could you not be excited about Jaire?" Head Coach Mike McCarthy said. "You could see it since the day he arrived. He walked into the building with so much confidence. He has a positive light that shines on him. It's infectious."

Williams has played with some of the very best cornerbacks of his generation in Charles Woodson, Patrick Peterson, Al Harris, Sam Shields, Casey Hayward and Joe Haden. Yet, the former Pro Bowler admits he hasn't been around a rookie cornerback quite like Alexander, calling him "one-of-a-kind."

If Williams hadn't known Alexander was the Packers' rookie first-round pick, the veteran says he wouldn't have been able to tell based on how Alexander carries himself on the field.

It isn't rare for rookies to pick up things quickly in the classroom in Williams' experience, but what separates Alexander is how he's integrated those lessons directly into his play rather than just relying on his talent and ability. As an added bonus, the energy Alexander possesses rubs off on the entire defense.

"Ja' is one of the young guys who has an intangible about his self that you can't really coach," Williams said. "He has an impact on the team just with his energy. It was great to see him healthy, so he can come out and show what he can do. He's been doing it when he's been on the field."
