Not unrealistic at all; I'm not sure it will happen, but it's certainly a possibility and probably more likely than not. Right now, I think we are, at worst, the 3rd best team in the conference in light of the Tennessee suspensions, and I personally think we're better than Ole Miss, although that is close, and Kentucky is still very young and may be prone to some off nights.
Both Arkansas games are wins. Georgia and Auburn are wins. @Bama should be a win. LSU should be a win. I'm not saying we're guaranteed to win all those, but I think there would be some problems if we didn't. That's 6 wins right there. We can certainly go 2-2 among the Ole Miss games, and on the road against Florida and Vandy. I still don't think Florida is great. They got hot early, but they have definitely cooled down, and we're better than them. Vanderbilt is decent and may be a good road test, but again, we're better. We should split with Ole Miss and given our history, I wouldn't completely rule out a sweep for us.
The bottom line is that the schedule from here on out is lined up very favorably for us. It's very possible for us to run the table after the Kentucky game, as well. We have a realistic chance at 4 or fewer conference losses this year.
