As the Raiders prepare for next week’s draft, general manager Mike Mayock said Thursday that a big element in the team’s improvement rests on two members of last year’s draft class.

The rookie seasons of wide receiver Henry Ruggs and cornerback Damon Arnette were a mixture of momentary flashes, injuries, setbacks and an obvious need to get bigger, stronger and better.

So as they go through their first full offseason as NFL players, Mayock is confident both are on the cusp of being the type of players the Raiders believed they would be upon drafting them.
