OAKLAND, Calif. – Tramon Williams has been around a lot of talented young cornerbacks during his 12-year NFL career, and in his experience, there's one overriding quality that allows rookies to contribute early on.

Don't make the game bigger than it is.

When the Packers veteran cornerback looks at Jaire Alexander and Josh Jackson, Williams sees two budding playmakers who fit that qualification to a T.

Despite a 13-6 preseason loss in Oakland on the scoreboard, Green Bay's first two picks in the 2018 NFL Draft were at it again inside the Oakland Coliseum on Friday night.

While Jackson nearly came away with his second pick-six in as many games, Alexander notched his first pro interception off Raiders quarterback Connor Cook in the second quarter.

"Both of these guys, they respect the game as much as possible, but they fear nothing about it," Williams said. "That's the approach you have to take to this game because you're going to face some tough battles week-in and week-out. If you fear those battles, you're always going to come up on the short side of it, but if you embrace those battles, you have a chance."

Coming off a groin injury, Alexander only played 10 defensive snaps in the slot during his preseason debut last week against Pittsburgh. Against the Raiders, Alexander started opposite Williams as a boundary cornerback in the Packers' base defense.

The 5-foot-10 cornerback had his "welcome to the NFL" moment on the very first play of the game when Derek Carr completed a 49-yard pass to Amari Cooper through Alexander's coverage.

The rookie didn't panic. Going back to the sideline after a 32-yard Mike Nugent field goal, Williams could tell Alexander was going to be OK based on how he was conducting himself.

So when Cook left a pass intended for Dwayne Harris inside on a post route in the middle of the field in the second quarter, Alexander made him pay for it.
