Utah defensive back prospects Brian Allen and Marcus Williams had impressive workouts at the NFL Combine Monday, starring in the 40-yard dash and vertical jump, respectively.

Allen, at 6'3" and 215 pounds, ran the 40-yard dash in 4.48 seconds — the 20th fastest time in the defensive backs group. Allen, who had 35 tackles, a sack and four interceptions for the Utes in 2016, also finished with 15 repetitions in the bench press drill, a 34.5 inch vertical jump and a 117 inch broad jump. Allen was the second fastest prospect in the three cone drill, finishing in 6.64 seconds, and ran the 20-yard shuttle in 4.34 seconds.

Williams, who led the Utes in interceptions with five last year to go along with 64 tackles and two forced fumbles, was explosive in both the vertical jump and the broad jump. His vertical jump at 43.5 inches was the second best of the group and he finished eighth best in the broad jump with a 129 inch effort.

He ran the 40-yard dash in 4.56 seconds and finished the bench press drill with 14 repetitions. The Utah safety also finished fourth in the 60-yard shuttle with a time of 11.26 seconds, 12th in the three cone drill with a time of 6.85 seconds and completed the 20-yard shuttle in 4.2 seconds.

Williams is rated as the third best free safety prospect in this draft by CBS Sports and the 67th prospect overall — projected to be selected in the second or third round. Allen is rated as the 44th best cornerback and 387th prospect overall and is projected to be an undrafted free agent.
