Ankrah is my was my first thought. Keep in mind, Meredith has been thought of as a candidate to move to the interior. I remember hearing that he was playing around 260 before the bowl and has some room to grow. This gives us a great opportunity to get more talent on the field. (Cam, Crick, Allen, Stein - unless he moves to OL - Ankrah... maybe Owa!)
IIRC Josh Williams was injured for the majority of the season, otherwise he would have seen some playing time. Indeed our D-line is going to be nasty for a few years running.
There were a couple of times this year where Larry Asante got banged up and PJ Smith came in with little to no drop off. PJ will be a different type of safety and not quite the head hunter like Asante was, which I believe is good and bad. I think PJ will look more like a Josh Bullocks at Safety.
Also with Ankrah just remember by the end of last season he was getting reps in practice with the #1 defense. He was definitely brought in to play right away but couldn't get the playbook down at the start of the season so they red shirted him. I believe about mid season he finally got it but the coaches weren't gonna burn a full year for a few games.
We'll see but theres no reason to really down grade these guys on their "hype" we do it every year, we're just being fans...
