Whether it's measurables, style or body types, there are many ways to compare players. With style comes fit. That affects how these committed prospects fit into their future college systems and if they are poised for immediate production.
Here's a look at the top 2019 QB commits and their comparisons:
Spencer Rattler, QB-DT
ESPN Junior 300: 16
Committed to: Oklahoma
Compares to: Deondre Francois, FSU
This comparison is primarily due to both players' effortless release of the football -- a smooth, loose and compact stroke that jumps off their hand. Rattler is a slightly better runner than Francois, which is an ideal fit for Oklahoma's offense.
How he fits: To be able to redshirt would be ideal, but Rattler's physical ability could find him in the No. 2 spot behind Kyler Murray. He is an ideal fit for the run/pass option game and could be used as a designated runner more than Baker Mayfield was.
Bo Nix, QB-PP
ESPN Jr. 300: 56
Committed to: Auburn
Compares to: Jarrett Stidham, Auburn
When you look at Stidham coming out of high school and now at Auburn, you'll see that Nix has the same development trajectory. Both are deceptively good athletes with excellent release mechanics.
How he fits: This is going to become an interesting QB battle once Nix gets on campus as he will likely be in direct competition with 2018 signee Joey Gatewood. Nix isn't the athlete Gatewood is but will be ahead of the curve in the passing game and is a good enough runner to do what Stidham does in this offense.
Roschon Johnson, QB-DT
ESPN Jr. 300: 63
Committed to: Texas
Compares to: Kellen Mond, Texas A&M
Johnson and Mond are similar due to their upside. As with Mond coming out of high school, Johnson has a high ceilings but isn't quite polished. Both prospects are good athletes, have a live arm and are dangerous true dual-threat types who will only progress as passers.
How he fits: Johnson is the closest thing to what Tom Herman has wanted at quarterback since he got to Texas and similar to what Herman had in Braxton Miller at Ohio State.
Dylan Morris, QB-PP
ESPN Jr. 300: 111
Committed to: Washington
Compares to: Brett Rypien, Boise State
In typical Chris Peterson fashion, intangibles, feet, accuracy and feel for the game trump physical tools as long as there are enough tools to do the job. Jake Browning could be used here as well as Rypien when comparing Morris, who like Rypien has an "it" factor.
How he fits: Considering Washington took two QBs in the 2018 class as well as Georgia transfer Jacob Eason, Morris is in a great position to redshirt and develop, which would be best for him. Also, expect one of these quarterbacks to transfer at some point.
Dwan Mathis, QB-DT
ESPN Jr. 300: 220
Committed to: Michigan State
Compares to: Manny Wilkins, Arizona State
Wilkins was underrated coming out of high school and so is Mathis. Good size and stature as both players are not only good athletes but good passers, too. As with Wilkins, Mathis has a high upside to develop as a dangerous RPO threat.
How he fits: He will have the luxury of redshirting or getting into the two-deep since the Spartans have a solidified starter in Brain Lewerke who just completed his first full season. Mathis will bring far more running experience to the quarterback room than what Michigan State currently has, which should make them more difficult to defend.
Jaden Johnson, QB-DT
ESPN Jr. 300: 253
Committed to: Louisville
Compares to: Elijah Sindelar, Purdue
Big, strong-armed and athletic. Both have the look of classic dropback passers but are deceptively good athletes and strong runners. Ideal measurables for the position.
How he fits: This will depend on whether Jawon Pass can make the next jump. If the expected successor pans out, Johnson could find himself competing for the the No. 2 spot as a freshman.
