Which SEC program takes the biggest step back next year?

The candidates:

Missouri - Lock has covered up the fact that this is a program with inherent roster deficiencies almost across the board for a couple years now. If they aren't still scoring 40+ every week after Lock leaves, they'll be in trouble.

Kentucky - This is an upperclassman heavy two deep with two high end NFL prospects (Snell and Allen) which allowed them to win a lot of close slugfests. The bottom line though is Kentucky has bottom tier SEC talent overall and lose all the best parts of this year's team.

Auburn - A coach on the hot seat with a new QB and players that generally don't fit what that coach would ideally like to do offensively, all in the toughest division in the country, is not a recipe for success. Not sure that are at too big a risk of truly taking a step back given they went 7-5 next year, but I don't think they'll be very good next year and it will probably be Malzahn's last.

Mississippi State - Losing Fitzgerald and all the best parts of that great defense will hurt, and if they want a QB who can execute what Moorehead wants to do offensively they could be starting a true freshman.

Ole Miss - I only put them on this list because they could go from bad to "worst P5 team in the country" bad. Looking at their schedule and what they lose, I genuinely expect them to go 2-10.

Personally, my money is on State or Kentucky. I think both go from fringe top-15 teams to potentially not making a bowl game next year. The winner of their H2H matchup will probably finish 6-6 and the loser 5-7. I think OM is already bad enough that I can't consider even 2-10 the biggest step back.
