Some prospects saw their stock slide at NFL Scouting Combine

INDIANAPOLIS — Many headliners boosted their draft stock at the NFL’s annual scouting combine with a wonderful workout, a dazzling 40-yard dash, a brilliant bench press or, in Kyler Murray’s case, just standing up straight.

Mississippi State edge rusher Montez Sweat and Ole Miss wide receiver D.K. Metcalf were the big winners along with Murray , but others saw eyebrows raised and their value lowered after costly injuries, bad interviews or pedestrian performances.

They’ll have to do better in their pro days and private workouts ahead of the draft in late April.

One of the biggest disappointments was potential first-round pick Jachai Polite, an outside linebacker from Florida who put up unimpressive numbers in the 40 (4.84 seconds) and vertical jump (32 inches) before ending his workout Sunday with a sore hamstring.

Clemson’s hulking defensive tackle Dexter Lawrence strained his left thigh running the 40 and sat out the remaining drills, disappointing scouts eager to see how the 350-pounder performed after missing the College Football Playoff because of a positive test for a performance-enhancing drug.

Lawrence’s college teammate, linebacker Tre Lamar, hurt his right shoulder on the bench press, and highly touted LSU cornerback Greedy Williams didn’t compete Monday after suffering cramps.

The most serious injury came Sunday when Ohio State cornerback Kendall Sheffield tore a chest muscle while heaving 225 pounds in the bench press drill. A torn pectoral typically requires surgery and a year’s recovery.

More disconcerting to teams are the players who can’t use injury as an excuse. That group this year included:

—Mississippi left tackle Greg Little. He labored through the on-field drills and posted poor numbers in the 40 (5.33) and vertical jump (25 inches). Those were among the worst for O-linemen and he skipped the bench press altogether.

—Florida Atlantic running back Devin Singletary. The Owls’ 5-foot-7, 203-pound playmaker piled up 3,300 yards and 54 touchdowns the last two seasons. But his hopes of shedding concerns about the level of competition he faced took a hit with a disappointing 4.66-second 40-yard dash.

—Georgia running back Elijah Holyfield. His status as one of the few standouts in a rather weak running backs class took a hit when he was clocked in the 40 in 4.78 seconds, slower than the trio of punters and kickers who ran the 40 at the combine. Among running backs, only Wisconsin’s Alec Ingold ran slower than Holyfield.
