I have a tough time with Wills over Becton. I understand that Wills is more polished, but IMO they both are best run blocking and I rate Becton as the more athletic of the two. I think Becton has the potential to develop into a significantly better pass blocker.
If you asked me...Simmons, Wills or Becton? It is pretty close at this point. I do believe Simmons is gone by the time the Cardinals pick, but if they did select him, it would be interesting to see how they used him defensively. Campbell was signed to start and is a pretty good player. Starting S spot would be the most apparent opening.
