It shows up with regard to how quickly he gets to the edge. Just go and rewatch the Florida and Alabama games. Jalen is explosive at getting to the edge. His weakness is he doesn't have great long range speed.
His 40 at the combine should be crazy. Sub 4.55 if I had to guess. But he can't keep building on that initial speed like a Fournette or Henry where if he gets daylight he's gone.
You're crazy.
