Id be shocked if he was part of the 2014 class. This year is just not a great year for DTs reguardless of ND staff being picky as far as mold. Its comparable to last year not being a strong class with Middle Linebacker. This years class is not great at MLB guys, but better than the 2013 class as a whole. Not ND's fault, but Hayes can play inside or outside, but just from a shear talent now/potential in 2-3 years, there just isnt a lot of great prospects out there.
Id take Elam in a heartbeat, but he is probably farther away from being ready to play than Nix was. Nix has a drive that many dont have and that is why he is successful, and the jury is out on Elam to this point. He seems like a great kid but college life is just a 360 from the situation he is in right now. Discipline is going to make or break this kid at whatever school he chooses.
