Whether and how much the Combine’s events matter is up for constant debate, but we doubt Byron Jones would have been drafted in the first round in 2015, for example, without his Combine world-record broad jump. Physical attributes, though just one piece of the puzzle that is a player’s pre-draft evaluation, can’t hurt.

Below are the best numbers for the core events — 40-yard dash, bench press, vertical jump, broad jump, three-cone drill, 20-yard shuttle and 60-yard shuttle — since 2006, or what the league calls “recent” history.

The NFL does not keep Combine records, so these marks are unofficial.

Bench press

Record holder: Stephen Paea, DT, 2011 Repetitions (225 pounds): 49 Yeah, but: Paea’s 49 reps were deemed a record in 2011 even though defensive tackle Justin Ernest pumped out 51 reps in 1999. Top five since 2006:

Record holder: Chris Conley, WR, 2015 / Donald Washington, CB, 2009 Height: 45. 0" Yeah, but: Safety Gerald Sensabaugh set a Combine record with his 46-inch vertical in 2005, a year before the NFL’s recency cut-off. Top five since 2006:

Broad jump

Record holder: Byron Jones, DB, 2015 Length: 12'3" Yeah, but: Jones did more than shatter the Combine record — he set a world record with his jump that dropped jaws at the 2015 event. Top five since 2006:

Three-cone drill

Record holder: J. T. Thomas, CB, 2018 Time: 6. 28 seconds Yeah, but: Thomas went undrafted in 2018. He was signed by the Eagles as an undrafted free agent but was cut soon after. Top five since 2006:

Record holder: Jason Allen, CB, 2006 / Brandin Cooks, WR, 2014 Time: 3. 81 seconds Yeah, but: Four players — Kevin Kasper, Deion Branch, Dunta Robinson and Champ Bailey — posted better 20-yard shuttle times before 2006. Kasper’s time of 3. 73 remains the best. Top five since 2006:

60-yard shuttle

Record holder: Shelton Gibson, WR, 2017 Time: 10. 71 seconds Yeah, but: . . . Gibson was fast — no buts about it. He barely edged Brandin Cooks and Avonte Maddox (10. 72) for this record. Top five since 2006:
