Sio Moore (LB-Oak, Round 3, Pick 66)
After taking over a starting role in Week 2, Moore had a very solid rookie season and showed his skills against the run and as a pass rusher. While his 50 tackles (38 solo) may be underwhelming, Moore played well on the strong side of Oakland's 4-3 defense, a position that doesn't get as many tackle opportunities as the other linebacker spots. His 4.5 sacks ranked third on the team and Moore was every bit the speedy, instinctual player scouts saw at Connecticut, which helped him show well in coverage as well. The Raiders might have a lot of turnover on both sides of the ball in 2014, but Moore should stick.
