FAYETTEVILLE, Ark. -- Alabama coach Nick Saban was not pleased Saturday with the defensive performance of his top-ranked team in a 65-31 victory over an Arkansas squad that has not won since Week 1.

"I don't think that you really beat the other team when you give up 31 points, like we did today," Saban said, "at least on the defensive perspective."

The Razorbacks' point total was the most scored against Alabama in 20 games, dating to a 35-31 loss to Clemson in the College Football Playoff National Championship to close the 2016 season, and the most scored by an SEC opponent against a Saban-coached team since a 48-43 win over Ole Miss in September 2016.

"We need to coach them better," Saban said after the Crimson Tide's 78th consecutive victory over an unranked opponent. "We need to prepare them better. They need to be able to make adjustments in the game better.
