It will be interested to watch. Their run defense will be good again too many pieces coming back that made it a Top 20 run defense in 2015. They were strong in almost every defensive category except for scoring defense and passing yards allowed. The back end has to get better to be a Top 10 defense.
Good depth at the DT position as well, Bailey, Shortridge, Richardson, Brown, Hearns and Williams. We will have to see how a couple of red shirt guys come along i.e. Robinson. It is always hard to replace someone like Rankins, but they should be able to hold their own.
LB-Fields, Kelsey, Thomas are all proven guys. I am not sure on the depth here. I am not counting on Young. That injury could have been a career ending injury which sucks for him. He was becoming a good pass rusher. They need to find someone that can replace him. RS Greenard/Caban maybe an option. This is probably the one position that has the most question marks going into the Spring. They are still recruiting LB hard.
Secondary-had issues which led to being ranked around 50th in pass yards allowed. Wiggins was solid all year that spot is locked down. Williams did a really good job most of the time. The three people were picked on last year where JHC, Reeve & Washington. A big play happened it was on one of these three. JHC and Washington will be back which will only make them better. They are both good in the run game and will have to improve their coverage skills. Alexander/JUCO will push at CB. I am not sure if anyone will push JHC. Pass and Smith will fight for the spot left open by Reeve graduating. I think they will both be quality nickel or SS.
