Eye-popping performances at the NFL combine often -- but not always -- can improve a player's draft position. ESPN.com researcher Ryan McCrystal has charted the best numbers in various combine drills since 2000. Please note: These are numbers recorded only at the combine, so any players not participating in drills (such as Reggie Bush) are not included. Also, 40 times are unofficial since they are recorded by two different timers; the best time is the one generally used.
