The Oakland Raiders wrapped up three days of organized team activities this week.

The biggest takeaway from the first media day was the amount of key players who were limited participates.

Nonetheless, plenty of questions remain as the team gears up for training camp with six more OTA sessions next month.

Here are the five biggest question marks after the Raiders latest OTA.

Who is the kick returner?

The Raiders cut and signed Robert Herron already in camp. Andre Debose also suffered injury.

That leaves last year’s returners TJ Carrie and Taiwan Jones. Jones fumbled the ball on two kick returns last year, but he was the best player at the position.

Carrie could fill the role, but he should concentrate on winning a cornerback role.

Are there new backups in the backfield?

Derek Carr and Latavius Murray solidify the Raiders starting backfield. After the Pro Bowlers, the competition is open.

The Raiders drafted two key rookies in the middle of the 2016 NFL Draft. Insert running back DeAndre Washington and quarterback Connor Cook.

Both players have impressed in OTA, according to reports. They could dethrone incumbent backup quartback Matt McGloin and running back Jones.

The aforementioned veterans are pricey, and from previous regimes. That could mean their days in Silver and Black are numbered. Hopefully, fan favorites McGloin and Jones will keep their roles as key reserves.

What will the safety position look like?

The Raiders moved 2014 fourth round pick Keith McGill from corner to safety. The lengthy prospect should have played the position from the beginning.

Nonetheless, McGill already looked impressive during drills. He could find himself battling for a role. The Raiders have veteran Nate Allen and Rookie Karl Joseph coming off of injury. Free agent acquisition Reggie Nelson did not participate in OTAs either.

McGill will need those reps if he wants to keep a spot on the roster and find himself in the safety rotation.

Do the Raiders have the best lines in the game?

This was not exactly news. The Raiders offensive line allowed Derek Carr to finish among the league’s least pressured quarterbacks. The defensive line also made tons of acquisitions via the draft and free agency.

That said, will the Raiders have one of the best groups in the league?

It sounds like it by the friendly smack talk the Raiders threw at the Broncos.

Will the Raiders go to Vegas?

The Raiders OTA happened on the same day as the NFL Spring meetings. Although potential relocation to Las Vegas was not on the Agenda, it took over headlines.

Hopefully, the Raiders will figure this one out as camp approaches.

Either way, these shorts and shirts practices do not do much other than establish comradery with teammates and familiarity with the playbook.
