Jonathan Fuller reviews the most memorable NFL Scouting Combine performances in recent history, focusing on the skill-position groups and how they changed their fantasy football trajectories.

With football season quickly fading into memory, the NFL world will soon turn its attention to the NFL Scouting Combine. This is both an exciting and dangerous time for those of us who try to project future NFL production for incoming rookies. It is easy to become enamored with the player who runs a blazing 40-yard dash or jumps out of the gym, but they still need to be a good football player.
Every year, there are players who make a name for themselves in Indianapolis and significantly improve their draft stock. The NFL Scouting Combine results are important data points that need to be considered, but it is equally important to make sure that they don't dominate the narrative just because they're the most recent information we have.
I have three main rules for evaluating Combine performances:
To be clear, being athletic is definitely a positive, but we don't want to overrate it. Many of the best players dominated at the Combine. Guys like Cam Newton, Julio Jones, Myles Garrett, Calvin Johnson and Luke Kuechly have some of the highest RAS scores in history, but they were also great football players. This is why it's rarely helpful to view individual data points in isolation. To properly evaluate prospects, we have to take all the information together and add context.
This article is going to focus on fantasy-relevant players, but there are also plenty of breakout stars at other positions. Last year saw Nick Emmanwori and Shemar Stewart post two of the best Combine performances in the history of their positions, and they went on to have very different rookie seasons. Emmanwori was a star for the eventual Super Bowl Champs, while Stewart struggled to make an impact on the stat sheet before ending the season on IR. Just further evidence that athletic testing is only part of the equation.
The clearest cautionary tale of the last few drafts, Anthony Richardson put up arguably the greatest NFL Combine performance of all time at the QB position. Running a 4.43-second 40-yard dash, jumping 40.5" in the vertical jump and showing off his tremendous arm strength had coaches and scouts thinking about his incredible ceiling.
Before the NFL Scouting Combine, Richardson was considered by many to be a fringe first-round prospect because of his lack of experience and poor accuracy in college. His performance in Indianapolis vaulted him into the top-10, and he ultimately ended up as the fourth-overall pick.
In hindsight, I don't think that assessment was wrong. The pros and cons of Richardson's game were clear and obvious. He has all the physical tools you could ever want, but he lacks accuracy and consistency. I can understand teams wanting to take the chance that they could develop him into the next great dual-threat QB, but it hasn't worked out so far.
For what it's worth, Richardson does have one of the most impressive throws in recent memory.
No article about NFL Combine breakouts would be complete without the current 40-yard dash record holder. Xavier Worthy set the Combine ablaze with a ridiculous 4.21-second 40-yard dash in 2024.
In my opinion, this falls more in the double-counting bucket. We already knew Worthy was really fast. Whether he ran a 4.21, 4.25 or even 4.30 wouldn't have really changed that fact. But the headlines generated by a record-breaking run and the potential to draft "the fastest man in NFL history" helped propel Worthy up draft boards and ultimately made him the 28th pick of the first round by the Kansas City Chiefs. Time will tell whether that was a smart selection or not.
Coming out of Penn State, Barkley was viewed as a high-level prospect after a great college career. However, the NFL was deep in the era of debating whether running backs matter or not. Barkley's unreal workout at the Combine, while weighing in at 233 lbs., was enough to convince the New York Giants to pull the trigger and take him second overall in the NFL Draft.

In a previous era, Saquon would have been a no-brainer top-10 pick, but in the late 2010s, it was a real debate. His selection by the Giants was controversial and a popular topic on sports talk shows. Interestingly, both sides kind of turned out to be right. Barkley has been a great player in the NFL, but he couldn't elevate the New York Giants. When he moved to a better situation in Philadelphia, he put up historic numbers and won a Super Bowl.
This is a cautionary tale in a different way. The Giants were right on their player evaluation, but wrong about how much of a difference he could make for their team. From a fantasy perspective, this is less relevant because Barkley still had some good seasons in New York, but his full potential wasn't unlocked until he joined a more talented roster.
Another former 40-yard dash record holder, John Ross, saw his draft stock skyrocket after the Combine, and he ultimately went ninth overall to the Cincinnati Bengals. This turned out to be a massive mistake as Ross only ever played 38 career games and totaled just 963 receiving yards.
Ross is frequently cited as one of the biggest busts of the 2010s and the poster child for what can go wrong when Combine hype gets carried away.
Still tied for the NFL record vertical jump at 45", Chris Conley made headlines for his leaping ability and it ultimately helped him secure third-round draft capital. Conley was never a star in the NFL, but he went on to have a solid career. Perhaps most importantly, Chris Conley once did a YouTube livestream with Fantasy Life's own Peter Overzet. His vertical may not have had anything to do with it, but that makes him a winner in my book.
While the history of breakout stars at the NFL Combine isn't great, there are some huge hits that we need to consider as well. Chris Johnson is one of the best examples of a player who saw his draft stock surge following a record-setting 4.24-second 40-yard dash and went on to have a great career. The Tennessee Titans selected Johnson at 24th overall, and he put up 1,400+ scrimmage yards in each of his first six seasons, including the legendary 2,000-yard rushing season in 2009.
Johnson is an interesting case study because his prospect profile wasn't all that great outside of his performance at the NFL Combine. He only had one year of strong production while playing four seasons at East Carolina. Without his 40-yard dash result, he probably would have fallen quite a bit later in the NFL Draft, and who knows how that would have affected his career.
My main takeaway from reviewing these NFL Scouting Combine breakouts is that we need to be extremely skeptical of the workout warriors who have very little football production to speak of. When athletic testing supports the ability of a productive football player, it is all systems go. When athleticism is used to project what a player could be, but there is no on-field evidence to support that projection, it should be a massive red flag.
