The team played significantly better after Gaither replaced Ro in the middle but that was as much improvement by subtraction as it was anything that Omar did with the team. Gaither played in the Raiders final 7 games last year and started 4 out of the last 5. He had 20 tackles (10 solo) in that time span. For his career he has 334 tackles, 2 forced fumbles, 2 fumble recoveries, 6 sacks, and 18 passes defended.
Gaither was originally drafted by the Philadelphia Eagles in the 5th round of the 2006 draft. He stayed with the Eagles for 5 seasons where he started 36 of the 67 games that he played in. He then played on the Carolina Panthers in 2011 for 10 games with 4 starts. After that he moved on and was in training camp with the Texans in 2012 before becoming a member of the Silver and Black. The 6'1, 235Lb linebacker certainly has plenty of experience to be a quality depth player.
The signing of Gaither does make one wonder about the current health of Miles Burris who is suppose to be Nick Roach's backup and wingman but is still coming back from off-season knee surgery. Gaither is a player that the Raiders had originally wanted to move on from in favor of Burris but with Miles still unable to participate in practice they had no choice but to bring Omar back. Hopefully Miles comes back strong but if he is out longer than expected Gaither has already showed capable of holding his own.
Many fans had felt like this move should have been made anyway and will welcome back Omar with open arms. He is worth bringing in as depth and even if he ends up not making the final roster he is still a player that will make the people around him have to compete harder. He is an experienced veteran and a welcome addition back to the Oakland Raiders.
