Here is a list of sparq scores (
https://3sigmaathlete.com/rankings/ol/). Sparq only measures athleticism and it is weight/height adjusted. The percentiles are just the average for that position in the NFL, so 50% is the NFL average and very good.
Elflein for example is in the 2.2 percentile so 97.8% of offensive linemen in the league are more athletic. OL are usually the least athletic group so everyone on the defense will have an advantage over him. I'm assuming it would be like a bell curve where most players are around 30-70th percentile because a lot of the top athletic testers are rare (and usually more athlete than football player) and the low testers are at a disadvantage.
Toth's competition and intelligence go in his favour, but his athleticism is concerning.
This has nothing to do with anything, but I wonder if the OL players in college have stronger academic performance than other position groups. It seems like every year there are OL prospects with masters degrees or degrees in STEM fields. I can't imagine playing D1 football and getting a degree in mechanical engineering.
