Arkansas has a lot of unknowns at this point. They have to replace their QB, best two RB's, a couple of very good O-linemen, and their best pass-catching playmaker at TE. Their defense should be improved but will they be elite? Probably not.
The last few years Arkansas had a poor start to the season but played better in the 2nd half of the year. I wish this game was in September because they are playing us at the best time for them. That doesn't mean I think they'll beat us. They will simply be a tougher team in November.
This game and really our season will come down to can we stop the run. If our LB's are still healthy, then I think the answer will be "yes." If we have some injuries and have to play nickel the whole game, then we better hope that the offense plays a great game.
Also, I've been to a game there, and while the town, campus, and stadium are surprisingly nice, the calling of the hogs chant is beyond obnoxious. It's similar to nails on a chalkboard.
