Brock Purdy: 40 yard time and speed evidence
The reviewed record lists 4.84 seconds. Source setting: compiled combine record. Read the event notes before comparing that mark with another workout.
Where the time comes from
The NFL workout video verifies a 4.84 second sprint in 2022. The historical table records a 27 inch vertical, a 7.21 second cone and a 4.45 second shuttle. It leaves broad jump and lifting blank.
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.
San Francisco selected the Iowa State quarterback with the final pick of the draft. His predraft size and running marks form one dated snapshot. A search for lifting repetitions has no numerical answer in the reviewed record.
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
The lifting and broad jump questions have no listed result in the reviewed table. The 27 inch vertical is a different test and cannot fill either gap. The NFL sprint video gives readers a direct way to check the 4.84 running mark.
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.
