The RotoViz Scouting Index – 2019 v 2.0 Post Combine Updates

With the combine complete, Dave Caban takes a look at an updated version of the RotoViz Scouting Index.

If you’re unfamiliar with the RotoViz Scouting Index (RSI), check out Version 1.0 for more background.1 In a nutshell, the RSI aggregates and compiles NFL prospect rankings from a variety of more traditional scouting outlets and helps in approximating a player’s draft value.

Version 2.0 includes some significant changes within the index. However, some of these changes are counterintuitive. I was expecting to see players who struggled at the combine, such as Devin Singletary, plummet in the rankings. However, he and other prospects who posted disappointing measurables managed to climb up the RSI. In subsequent posts, we’ll consider more closely if there’s important information we can glean from particular player’s combine results.


Tyree Jackson made the largest jump of any passer.2 This is clearly the result of his strong combine performance. Jackson profiles as an above-average athlete at his position and possesses incredible speed for a player of his size

Generating a list of comparable players by equally weighting height, weight, forty-yard dash, bench press, vertical, broad, shuttle, and 3-cone performance provides an encouraging picture of his ability to contribute as a rusher in the NFL.

Daniel Jones does not project as an NFL passer given his college production but remains fourth in the RSI. His combine performance confirmed that he’s athletic, but wasn’t enough to change my opinion that he has little likelihood of seeing NFL success.

Running Back

Josh Jacobs was omitted by one of our sources in Version 1.0 but was included in this round. As a result, he now sits atop the RB RSI. Jacobs didn’t participate at the combine but his highly ranked peers failed to demonstrate enough athletic ability to shift the rankings.
Singletary ranked seventh in Version 1.0 but managed to climb to fourth. However, his combine performance left a lot to be desired, so it’s surprising that he managed to rise in the rankings. His speed score of 86 is below the 25th percentile, he lacks agility, and at 5 feet 9 inches is one of smallest backs in the class. The scouts aren’t turned off by his measurables, and this could be thanks to the impressive production he recorded at FAU. In three seasons, he accumulated with over 4,600 scrimmage yards and 67 touchdowns.
Devin SIngletary Combine
Backs such as Dalvin Cook have overcome athletic deficiencies and found success at the professional level. That said, of Singletary’s 20 closest athletic comps, Elijah McGuire, Devonta Freeman, and Mike Gillislee are the most exciting.3
Devin SIngletary Comps
In contrast, fellow “small back” Justice Hill had a solid combine and generates a list of comps that includes LaDainian Tomlinson, Alvin Kamara, DeMarco Murray, Jerick McKinnon, and Joseph Addai. While not as prolific as Singletary, Hill did accumulate 3,843 scrimmage yards and 31 touchdowns in three seasons at Oklahoma State. As the dust continues to settle, Hill may be able to crack his way into the RSI, but presently he’s a significant omission.

Wide Receiver

D.K. Metcalf’s insane forty helped to solidify his spot as the highest ranked wide receiver in the 2019 class. While his size-adjusted speed is phenomenal, his lack of agility is a cause for concern. Given that Metcalf lacks the collegiate production of a typical first-round receiver, his poor agility scores shouldn’t be entirely dismissed.
Metcalf Percentiles
Tremendous athleticism doesn’t guarantee NFL success either. As Metcalf is a rare specimen, it’s difficult to generate comps that are similar across all dimensions. Nonetheless, Julio Jones, the player he drew comparisons to after his combine performance, does make the list. That being said, many of his comps are large athletic players who failed to translate their strong athletic profiles into NFL production. It should also be noted that Jones’ agility score of 10.91 is nearly a full second better than Metcalf’s score of 11.88.
Metcalf Comps
Andy Isabella made a nice jump, but I was hoping to see Parris Campbell, who proved himself to be an elite athlete, get more credit for his tremendous combine performance. Campbell actually fell five spots in the RSI.

Tight End

Noah Fant’s fantastic combine solidified his position at the top of the TE RSI. While Irv Smith Jr. and T.J. Hockenson were impressive, Fant was exceptional.

Dawson Knox climbed from 10th to seventh in the second iteration of the RSI. Knox displayed solid agility at the combine. As he shared the field with Metcalf and A.J. Brown, his collegiate production is limited. Knox recorded just 39 receptions, 605 yards, and zero touchdowns in his 17 games at Ole Miss. But his rise in the RSI suggests that his athleticism may be enough for a team to take a shot on him and give him some early opportunity.
