Raiders coach Dennis Allen thought the three-day minicamp, concluded Thursday, went well, and is looking forward to seeing his players get the pads on at training camp in late July.

“It was a good camp,” Allen said. “We improved. … I like this football team. I like their mentality.”

Allen anticipates everybody being healthy and ready to go at the start of training camp. Second-year linebacker Miles Burris and rookies D.J. Hayden, Nick Kasa and Latavius Murray all have been out with injuries.

Oakland’s roster was gutted after a 4-12 season, and Allen likes the energy and focus he has seen from the players in his second year.

“There’s been a lot of change,” he said. “The thing I have been most pleased with is the mindset of this team.

“I know there’s a lot of experts out there that might think differently, but I like this football team.”

Briefly: The Raiders have signed third-round draft pick Sio Moore. The linebacker is the seventh of the team’s 10 picks to sign, with their top three picks left and merely a formality at this point. … Allen said he talked with running back Darren McFadden in the offseason about taking on a bigger leadership role and McFadden has done “a nice job.” … Second-round pick Menelik Watson got some reps at first-team right tackle for the first time in offseason workouts. He is trying to unseat returning starter Khalif Barnes … Allen said that backup fullback Jamize Olawale has “really improved” from the end of last season.
