The Raiders aren’t insulated enough in their building to keep from hearing a little of the external hype following their prize-winning offseason.

Oakland upgraded its roster significantly with the signings of left guard Kelechi Osemele, linebacker Bruce Irvin, cornerback Sean Smith and safety Reggie Nelson. And that’s all before next week’s draft, which is what general manager Reggie McKenzie is being sure to remind his scouts.

“I remind my scouts, don’t believe the hype,” McKenzie said Friday. “You still scout hard, still scout them the way we always have.

“We’re still going to grind. That’s just the way we do it. Jack (Del Rio) and I always talk about, we want to get to the playoffs and then, that’s when the season starts. We want to try to bring home the trophy.”

Del Rio, entering his second year with the Raiders, doesn’t have to remind his players anything like that.

“It’s not hard to remember who won the Super Bowl,” Del Rio said, referring to the division rival Denver Broncos. “We’ve accomplished a lot in terms of the work that we’ve done and we know there’s a huge mountain of work in front of us.”

For McKenzie, who has done an admiral job the past two drafts in selecting, among other talented players, defensive end Khalil Mack and wide receiver Amari Cooper in the first round and quarterback Derek Carr in the second, the pressure isn’t any less now that the roster isn’t full of Swiss cheese.

“Honestly, I think there’s more pressure,” McKenzie said. “I really do. You guys write about how good Khalil, Amari and Derek and all these guys are, how can that not put pressure on me? We’ve got to continue to get really good players in here. We’re looking forward to building on that.”
