I actually think Nix is a good fit for McVays system. If they are really considering him, I'd rather they trade down towards the end of the 1st rd and take him. That's assuming he's still there. I'm not saying they should draft him, but I wouldn't be upset if they did granted it wasn't at 19.
What is best in life? To crush your enemies, see them driven before you and to hear the lamentations of their women.
