Cutcliffe.
2012 Auburn wasn't as bad as their 3-9 record. They just gave up down the stretch. Gus walked into a talent-loaded team. Not to take anything away from what he has done, but he inherited a pretty good team.
Cutcliffe inherited a team that basically never won, has no resources, tradition, etc. and is taking them to the ACCCG.
What Cutcliffe has done - granted, not just this season but over the past couple seasons - is way more impressive.
