Just my opinion here, but it seems more like we took him as a project. He was far from being a polished player in college. Never had a double digit sack year. However he has really good physical attributes and I think that is what ultimately got him into the third round. I don't expect much from him this year, but with Mathis as his coach he could very well come on very strong.
To the OP, it's very hard to compare him to Tim Williams. Tim was thought of as being a 1st round draft pick. He fell for multiple reasons. Believed he couldn't learn a play book, a system player and drugs. Just because they were drafted in the same round, it's like comparing apples to oranges between the 2 kids.
