The Bulldogs have benefited from a relatively "easy" schedule (for an SEC powerhouse, that is), but they are definitely building momentum. If they beat Auburn and then steamroll GT, they will have done everything they could (outside of beating Bama in the SECCG). They could be an interesting test case for a non-champion making it to the playoffs.
Also, even if they do hiccup along the way, don't discount the possibility of 2 B1G teams. Wiscy looks like they will go undefeated in the regular season. And if PSU or tOSU only have one loss going into that conference championship game, that could prove interesting as well.
ACC is hoping Clemson doesn't lose another game in the regular season and that Miami keeps pulling out these miracles wins. Then if either of them wins the ACCCG they would definitely go to the Football Final Four regardless of what happens in other conferences. But a 2 loss ACC, B12, or PAC champion will have difficulty making the playoffs.
Could be an interesting year for ESPN (...err, the playoff committee).
Cheers,
