The Oakland Raiders remain impressed with first-round linebacker Khalil Mack.

He recorded a sack against the Detroit Lions last week.

Mack is still slowly adjusting overall to the NFL speed of the game.

Drafted fifth overall, Mack is expected to become an impact player by coach Dennis Allen.

“He has a lot on his plate,” Raiders safety Charles Woodson said. “Not just from the standpoint of him being a high pick and everybody expecting that ‘wow’ factor out of him, but as far as the plays, knowing the positions and different things they have him doing, there is a lot expected of him in that sense, too. You just allow him to grow as a player. This guy is going to be OK, and I think the sky is the limit for him.”

Clowney and plenty of other highly touted rookies have has rough moments during their first preseason outings as well, so there’s nothing unusual about it taking some time for things to come together for Mack. Based on his college exploits and size/speed mix, there’s every reason to believe big things will follow once they do.
