Latham certainly looks the part of an NFL defensive tackle, weighing in at just over 300 pounds.

However, in addition to his pure size, he's surprisingly quick for a big man, and showed that he's willing to learn and get better, spending some time one-on-one with defensive line coach Jethro Franklin, working on his technique on a bevvy of pass rush moves.

It's no secret that the Raiders are stacked along the defensive line, but as Head Coach Jack Del Rio always says, you can never have enough players who are disruptive and can get after the quarterback.

4. Wide Receiver Max McCaffrey

While McCaffrey may not be flying too far under the radar – he was one of the team's most talked about undrafted free agent signings – he was certainly impressive during Rookie Minicamp.

The former Duke Blue Devil is still an unfinished product and will need to spend some time in the weight room during the offseason, but he can definitely catch the ball and is a player to keep an eye on as the team prepares for Training Camp 2016.

While the three-day whirlwind was certainly overwhelming for the rookie participants, McCaffrey looked comfortable on the field, running through drills with ease and flashing impressive footwork.
