For 4-3 DE I think you have to consider Dumerville. He bounced around a lot, but so did Mecklenberg, in the same way...LB in 3-4, DE in 4-3. But he was drafted as a DE, so that is where I slot him. Rich Jackson is highly thought of as well, but he was before my time, so no first hand opinion.
Also hard to pass up Simon Fletcher. But not over the 4 listed. Wilson is another HM.
Alzado is a tough one. Great here, great for the dirt bags. But no denying the talent. Wont argue if others have someone else though.
Carter or Kragen. My memory is fuzzy on NT for some reason. Kragen sticks out a bit more for me...plus he made a Pro Bowl. Probably due to recency.
Punter, I go with Colquitt...best average with a significant number of punts, and none blocked.
I think Demaryius has passed McCaffrey, as much as I loved him. My sentimental pick for WR would go to Steve Watson though.
Champ over Thompson for CB, with Wright as the no brainer.
Safety is probably the hardest spot to pick for me. Picking two of Atwater, Smith, Foley or Lynch (but he was getting slightly old by the time he came to the Broncos)...to not make it.
