The Lions have the second pick in the draft.
Some talent evaluators believe the 23-year-old Suh, who played at Nebraska, is the NFL's best defensive tackle prospect to enter the draft in several years.
During his career at Nebraska, Suh appeared in 54 games and totaled 214 tackles, 56 tackles for loss, 24 sacks, four interceptions, three forced fumbles, one fumble recovery, 15 pass deflections and six blocked kicks. A single-season, career-best 12 sacks came in 2009.
The 6-feet-4, 302-pound Suh won the Outland Trophy, the Lombardi Award, the Chuck Bednarik Award and the Bronko Nagurski Award in his final college season. He was also named as the Associated Press player of the year and was a Heisman Trophy finalist.
