2021 Prospect Pro Day Data Added

2021 Pro Day data has been added. Pro Day times now display in the large NFL Combine Data table in italics when there is no combine data available, for all available years. You also have the option to adjust the data based on per position average difference in combine score and pro day score.

Individual player pages also contain the 2021 Pro Day info and can be accessed via the Player Search or the NFL Combine Data table for 2021.

Additional changes to Player Pages are also coming to utilize additional Pro Day information when NFL Combine Data is not available for a player.

If you are curious about how Pro Day scores normally compare with Combine scores, please see the Pro Day/NFL Combine Results Comparison Tool

Pro Day Comparison Tool Available

With the cancellation of the 2021 NFL Combine there has been increased interest in Pro Day adjustments.

This Pro Day Comparison Tool measures the average difference between Combine and Pro Day for the filtered criteria. Each available Event can be filtered by combinations of Position, Year(s), College, or Conference.

The Average Difference measures how much better the Pro Day is, on average, than the Combine. The Absolute Average Distance measures how far apart the scores are regardless of which is higher.

Fixed 2020 height and weight errors, many other fixes.

Fixed 2020 height and weight errors, many other fixes.

We had a major error that was showing initially reported height and weight for 2020 players instead of the actual combine measurement. This has been corrected. Thank you to those who pointed it out.

2011 Pro Day Arm Length and Hand Size were flipped. This has been corrected.

Randy Moss is a point of some contention and the sources of many error reports. Randy Moss data on NFL Combine results is gathered from a 3/13/1998 private workout for scouts. It is not from the official Marshall pro day or the NFL Combine. See this Randy Moss post for more clarification.

The pre-1999 data has some measurables listed as Combine when they may be Pro Day or Private Workout stats. Randy Moss is one of these and his data has been moved to a Pro Day.

Other fixes:

  • Darnell Mooney – is not 6’4″ 300+ lbs – data update error corrected
  • Randy Moss Workout Data moved to Pro Day Section
  • Additional Duplicate entries cleaned out/merged

Please report any errors you find when researching on this site. We will to our best to validate and make corrections.

Randy Moss Workout Data Clarification

Randy Moss Workout Data Clarification

We get a lot of comments about Randy Moss, including very well meaning correction requests notifying us that the data is incorrect. There is a discrepancy here that it is worth explaining. The data was technically incorrect under the NFL Combine Results heading where it was previously placed on the site, because Randy Moss did not attend the NFL Combine. This data is also not from his infamous Marshall Pro Day.

The Randy Moss data on NFL Combine Results is from a Private Workout on 3/13/1998. It does not technically belong in the “Pro Day” or “NFL Combine” category, though technically it is closer to a Pro Day and the data has been moved to that section.

The Sports Illustrated March 23rd 1998 Issue briefly mentions this private workout. Scouts contributing our data recorded 4.33 and 4.44 as the forty times run at the event, which was averaged into a 4.38 time. We are not certain why the reported 4.31 and 4.35 mentioned in the SI article were entered into the data as a single averaged 4.33 forty time.

Marshall sophomore wide receiver Randy Moss, the enigma of the
first round because of his troubled past, had an impressive
workout for the handful of NFL teams who watched him go through
drills at his school last Friday. In a 25[degree] windchill,
Moss ran the 40 in 4.31, 4.35 and 4.44 seconds–superb times
even in ideal conditions.

Sports Illustrated 3/23/1998

Scouts using their subjective judgement to calculate an average of hand-timed 40 times is one of the reasons that data collected at the NFL Combine after 1998 is vastly superior to times collected before that. The NFL Combine also uses video evidence to adjust electronically timed scores after the event to further increase the accuracy of the electronic time.

The times and scores from this private workout are more complete than anything else we have. The temperature is also worth noting.

We hope this clears up some of the confusion around Randy Moss’ pre-draft athletic testing scores.

2021 NFL Combine Cancelled

2021 NFL Combine Cancelled

The 2021 NFL Combine in Indianapolis has been cancelled due to the COVID-19 pandemic.

The NFL memo reported in full by Adam Schefter states that the NFL is developing a plan to obtain comprehensive medicals on all invited participants. The memo also states that club interviews and psychological testing will be done virtually and will be coordinated by the NFL. Universities will be asked to help to provide media interviews for invited prospects with NFL broadcast partners.

On the topic of athletic testing, the memo states:

“There will be no in-person workouts at the Combine. Instead, any workouts will take place on the individual pro days on college campuses. We will work with the schools to encourage consistency in testing and drills across pro days and ensure that all clubs have access to video from those workouts, irrespective of whether the club is represented at a particular workout. Rules governing timing and testing of draft eligible players with club personnel attendance at pro days will be sent in a separate Player Personnel memorandum.”

NFL Combine Results will attempt to gather all data from these officially regulated pro days, as we normally would.
