Mac Jones: 40 yard time and speed evidence
The reviewed record lists 4.72 seconds. Source setting: pro day compilation. Read the event notes before comparing that mark with another workout.
Where the time comes from
The 2021 table lists 4.72 seconds, a 32 inch vertical and a 116 inch broad jump. That draft cycle used campus workouts instead of the usual in person scouting event. These marks belong in a pro day comparison.
Speed is only one part of movement
A straight sprint measures elapsed time over a fixed distance. It does not measure top speed during a game, running with the ball or the ability to change direction. A start, surface or timing method can affect a comparison between events.
The Patriots selected the Alabama passer fifteenth overall. Their scouting report focuses on anticipation and ball placement as well as his campus workout. A running test cannot replace those passing skills when assessing a pocket quarterback.
How to compare the record
Compare the same distance, event type and timing method. A campus report and an electronic event result may use different setups. The reviewed sources here do not provide verified split times or a complete position ranking. Converting this mark into miles per hour would hide how acceleration changes during the run.
What to check for this record
A table titled by draft year can include campus results. For this class, calling every entry an Indianapolis performance would misstate the setting. His 116 inch broad jump equals 9 feet 8 inches, while the separate vertical entry measures upward reach rather than distance along the ground.
Questions readers ask
What do the timing units mean?
Each listed sprint value is elapsed time in seconds over 40 yards. It is not a top speed reading, an agility drill time or a verified split for part of the run.
Does a blank result mean a slow run?
No. A blank means the reviewed source has no recorded time. It cannot establish a failed attempt, a slow run or the reason for a missing result.
