Carr is right, Crabtree looks incredibly at ease out wide, and he certainly hasn't seemed to miss a beat during the offseason layoff.

It'll be exciting to see what Carr and Crabtree can accomplish in their second year together, and that all starts during OTAs.

4. Karl Joseph is working his way back

The Raiders selected safety Karl Joseph in the first round (No. 14 overall) knowing that he likely wouldn't be ready to hit the field until the team reports to Training Camp 2016.

Joseph has not taken the field with his teammates through the first three OTAS, but he has spent time on the side with the Raiders' training staff rehabilitating. Additionally, he's also been present during the defensive drills, taking mental reps and asking questions of defensive coordinator Ken Norton, Jr.

While it must be hard for Joseph to be sidelined, it's good to see that he's taking the proper steps to ensure that he'll be back on the field with the rest of the Silver and Black as soon as possible, and hopefully without too much of a learning curve in front of him.

5. The Raiders have built an imposing offensive line

Much has been made this offseason about not just the caliber of the Raiders' offensive line, but also the sheer size of the group.

From Donald Penn, to Gabe Jackson and newcomer Vadal Alexander, there isn't a small or undersized player to be found, and just seeing the group go through drills, it's evident that it's a unit of big, powerful men.

It's no secret that Del Rio and his staff covet size and power along the line, and the group that's been assembled in Oakland certainly fits that mold.

Personally, I'm excited to see just how physical they get once the pads come on at training camp.

6. Jihad Ward has raised some eyebrows
