He just isn’t athletically gifted. Only so much s&c is going to do. Burton was timed at 4.43 in hs and he spent time in uga and bama and ran 4.45 at the combine. No s&c is taking none athletic guys and making them athletic
I mean he did get a lil faster technically but based off his other numbers he just isn’t a explosive guy so doubt its much more that could’ve been done
