The Razorbacks only loss is to Bama. and they still travel to Baton Rouge later this month.
A 3-way tie of the teams all at 11-1 would come down to the head-to-head result among the top 2 teams in the BCS rankings, as long as they're within 5 spots of each other (and the 5 spot thing would be a certainty if they all go 11-1). So if Arkansas wins out but stays below both LSU and Alabama in the BCS standings, LSU would go to the CCG because of the win at Bama.
But if Arkansas wins out and Bama loses to Auburn, Arkansas would win the SEC West.
