It's difficult at that level when players move on after 4 years and often they don't even play a full 4 years, the coach has no control over that. And don't let "fans" get under your skin, I pull for the JETS but would never think of myself as a "FANatic" of any team, they don't live and die for me so I won't do it for them.
But yes Auburn had a great team a few years back and will again with the right recruting.
