Anthony Walker . 56. player. 28. The defense in general for the Raiders needs a lot of help as their collapse late last season proved. Having upgraded the front, next they have to find more help at linebacker. Somebody who can do more of the dirty work, making tackles and covering the middle. Anthony Walker played too heavy in 2016 but in 2015 he was all over the field for Northwestern from tackling, to coverage to blitzing the quarterback. If the Raiders keep his weight down, he’ll get things done.. LB. Northwestern
