I love both, but I think Nicks is more realistic.
I think Hardy goes late 1st. Nicks should still be around at #37 and he would definitely fill the role of the big roadgrader on the right side. There's also the Callahan connection at Nebraska.
I'd love heading into next season with this O-line:
LT D'Brickashaw Ferguson
LG Alan Faneca
C Nick Mangold
RG Brandon Moore
RT Carl Nicks
