Josh Jacobs' 18-yard touchdown run against Louisville was almost typical.
It was just a handoff the Alabama junior bounced outside for what looked like an easy run into the end zone. Only the block that got him there was thrown by a helmetless teammate.
Tight end Hale Hentges lost his headgear engaging the Louisville line but still sealed the edge to spring the score that put Alabama up 34-0. He only later found out that's against a rule that was not enforced on the play.
It's just natural instinct," Hentges said, reflecting more than a week later.
