Kentucky's stacked schedule

Much has been made of Kentucky's undefeated regular season. But how tough was it? They played ONE true road game in the non-conference season (at Louisville).  Most of the season they were the only ranked team in the SEC, and the team that became ranked late in the season (Arkansas) they played at home. They played some pretty good teams, but they managed not to play any of them (except the one) on the other team's court.
