FAYETTEVILLE, Ark. (AP) — DeVonta Smith returned a punt 84 yards for a touchdown as No. 1 Alabama scored 28 points in a span of 11 minutes in the first half and rolled past Arkansas 52-3. After the teams traded field goals, Smith started the Crimson Tide (10-0, CFP No. 1) barrage. Najee Harris scored consecutive touchdowns just 14e seconds apart and a final plunge from 1 yard by Brian Robinson Jr. had Alabama in cruising toward the Southeastern Conference championship game next week against No. 6 Florida. It was an otherwise quiet day for Smith, with three catches for 22 yards, but the receiver bolstered his surging case for Heisman Trophy consideration on one play. Arkansas lost for the fourth straight game.
