I really thought Trent Williams had a very solid workout on Day 1 along with Campbell. He may not be considered a "riser", but he is at least holding his ground, imo. He may have pushed himself back into the top 3 tackles anyway.
As far as Weatherspoon, maybe that's what all the talk moving him to ILB and giving him signal calling duties. I mean, if he's gonna continually chatter, might as well make it serve a purpose.
