That's not what he said.
Chris Brown asked Nix his thoughts on the draft not having much depth at the DE position. Buddy disagreed, felt this draft was deep at DE, but not at the top of the draft. Nix feels that depth at DE exists in the middle rounds, starting in the 2nd, not much depth at the top, not many in the top 10.
Didn't say he wasn't interested.
Edit: Brockers is a pipe dream, they won't be taking another DT. He can't play end in a 4-3, Chan has stressed getting a 4-3 DE not a tweener. Mock an offensive tackle, CB, or WR because those will the targets.
