In this particular comparison, I truly believe it boils down to identity, of which, NU has none.
Rich-Rod knows what he wants his team to be, and he employs coordinators in that vein and recruits players to that strength. Much like KSU, OSU, Mizzou , Utah, ORE, etc...
I have long said that this NU team has no identity, on offense or defense. Who are we? What stands out about this team or scheme to you? That is the first step; establishing who we are and who we want to be, the chips will fall after.
This team continually strikes me as a Frankenstein unit, a hodgepodge of players suited for different schemes, yet asked to play--and excel in ours.
It's odd. Maybe I'm off base, but my assessment of Pelini's tenure is...odd.
