Players who succeed in the NFL generally produced in college, too.

It's such a simple concept, but when you turn on your television for a little draft analysis, you'll hear more about a guy's hip swivel than his yardage market share during his final college season.

There's nothing wrong with analyzing film -- it's a great and needed way to evaluate a college prospect. There are other, nerdier ways to evaluate, though, too. Data-driven ways.

Again, if we know players who are successful at the NFL level were also good during their college careers, then we can analyze some of the production-related traits that NFL studs share in order to find prospects who fit the NFL mold. So let's do that.

Defining Success

If the title of this article sounds familiar, it's because JuJu Smith-Schuster), there were concerns (his production dipped during his final collegiate season).

Last year's study looked to our Andre Johnson), and some went to small schools (Pierre Garcon). And one didn't even play wide receiver in college (Julian Edelman). After weeding out some of these players, there was a sample of 31 studs.

Here's how the sample of successful NFLers compares to the 2018 class, with the class being defined as wide receivers who were invited to the NFL Combine and also played this past year. All of the averages below are taken from each player's final collegiate season.

The top-tier NFL wide receivers fared much better in college than the average of this year's class. That should be the least shocking thing you see all day. But which players stand out? Which players have usage concerns? Which players have scoring concerns? Do any players have zero concerns?

Usage Concerns

So, uh, here's the thing: this year's class is filled with red flags from a production angle. Of the 40-plus wideouts who are heading to the NFL Combine, all but four failed to hit the average reception market share (the percentage of receptions within their offense) number reached by our NFL sample.

*Didn't play the entire season.

One of the most complete prospects in this class from a production standpoint is James Washington, who battled alongside a lot of strong wide receivers in the Oklahoma State offense this past year. That's a big reason that we probably shouldn't be overly concerned with his usage profile, especially considering his receiving yard share and touchdown share within the Cowboys offense far outpaced his overall reception share.

You'll notice that Jordan Lasley is on the list, too, but he also didn't play the whole 2017 season due to a suspension. Lasley actually finished with the third-highest receptions per game rate among NFL Combine invites, and his prorated reception share is closer to 28%, making his usage less of a concern.

There's also Richie James. You'll see his name a lot on these lists, but it's not because he's an unproductive receiver. He just missed time due to a broken collarbone. Prior to 2017, James had 32.13% and 30.09% of Middle Tennessee State's receptions during his Freshman and Sophomore seasons, respectively. His production has been fine.

One guy getting a lot of love is Southern Methodist's Courtland Sutton. You can see Sutton in the chart above, showing off a not-so-great 24.03% reception share in the SMU offense last year, a number far lower than teammate Trey Quinn's 40.28%. While a lower reception share isn't the biggest deal in the world, only five wideouts in the NFL sample hit a sub-24% mark during their final collegiate seasons.

Receiving Production Concerns

We saw the successful NFL wide receiver sample average a receiving yardage market share of 35.89% during their final college seasons, and only two -- Michael Crabtree and DeSean Jackson -- saw yardage shares below 25%.

Only three wideouts who are in this year's NFL Combine hit the 35.89% average, though Alabama's Calvin Ridley was a close fourth. And plenty didn't even hit the minimum threshold of 25%.

*Didn't play the entire season.

The thing about Crabtree and Jackson is that they had other things going for them to combat their lack of receiving yardage shares. Crabtree, for instance, was an elite touchdown scorer in college. He also had a freshman season that was better than his final, sophomore year. And DeSean Jackson has one of the more unique skill sets we've seen from a wide receiver over the last decade with his speed.

A lot of the players on this list appeared on the last one, and some are relatively big names. In more ways than one. Analysts are into Equanimeous St. Brown out of Notre Dame, and had we only looked at last year's numbers (his Sophomore campaign) rather than this year's (Junior), we wouldn't have to talk about him right now. But his production dipped year over year, and while quarterback play surely had to do with some of that, we're also looking at shares within the offense. There's a lot of upside with St. Brown, but his production profile during his final year wasn't all that strong.

Scoring Concerns

Successful NFL wide receivers dominated the end zone in college. It was their home away from home.

Within the sample we're looking at today, the average receiving touchdown market share was 42.29%. The difference between that number and what we're seeing from this year's NFL Combine participants was largest among all market share categories.

Scoring matters.

Six wideouts in this year's class -- well, of the wideouts invited to the NFL Combine -- hit that touchdown share mark. That's reassuring. But there are lots with uninspiring scoring numbers.

*Didn't play the entire season.

If you had to point to one player as the wide receiver who'll probably be the first off the board in this year's draft, it's Calvin Ridley. His usage and overall production numbers were pretty solid, but things get troublesome in the touchdown department. Among these NFL Combine participants, Ridley actually had the seventh-lowest touchdown share in his offense this past year, and that ranking would've been even worse had Richie James actually played a full season.

For reference, the lowest touchdown share in the successful NFL wide receivers subset was 25.92%. And arguably (probably) the worst player within the dataset, Mike Wallace, hit that mark. Ridley's 17.86% mark is really concerning, but there's some hope in that his Freshman and Sophomore seasons saw a 29.93% and 29.87% mark, respectively.

This study last season pegged Mike Williams with slight scoring concerns (a 26.19% touchdown share), but the difference was that he had no real track record. Ridley does.

Fitting the Mold

If we only look at the average reception, receiving yard, and touchdown shares among our NFL subset and use that as a baseline, one player from this year's class makes the cut.

DJ Moore's production profile is otherworldly. If we were to place his final season numbers into the 31-player NFL sample, his reception share would rank third, his receiving yardage share would rank third, and his touchdown share would rank fourth.

Not bad.

If we want to be a little more liberal with the restrictions and throw out usage and reception concerns, we get the following:

Now, this clearly isn't the end-all to every single wide receiver debate out there. Utilizing final-year production numbers is just another piece to the puzzle. Film helps. Physical measurements help. Combine results help.

There's just no reason to ignore production because, as we know, successful NFL players were productive in college, too.
