I don't have much to offer based on what I saw in the spring game, as our D played everything very vanilla, for whatever reasons our coaching staff had for that.
I will say that we look much bigger at LB than we have in past years when we had Jake Fisher (5-10) and Sir Thomas Jackson (6-0) on the field at the same time. Smothers "looks" the part, he's a big guy and has a great build, listed at 6-2, 237. DeAndre Miller is listed at 6-3, 224, and looks really fast. Jake Mathews is 6-3, and listed at 214 but that's last years weight. He looks to me to be at least 225. He's big and quick. Scooby is listed as 6-1, 230 and honestly, he looks bigger and a bit slower. I hope I'm wrong there. Add in Keoni Bush-Loo at 6-4, 225 and Hank Hobson at 6-3, 227, and then Ware and Cobb in the fall, and we have FAR more depth and size at LB than we've had in years.
