Raiders OC Chip Kelly trying to make big change with Ashton Jeanty

Jeanty has what has become known as the "Halloween" stance in the backfield. It's comfortable for him, but it's not like the stance traditionally used by running backs. Rather than being in a "two-point stance" with a slight lean forward, Jeanty stands straight up in the backfield with his hands at his side.

He looks like he's stalking his prey like Michael Myers from the "Halloween" movies, which is where the nickname behind the stance comes from.

Again, it's worked out for him so far, but Kelly knows a thing or two about offense. More than likely, Kelly is trying to induce more explosion out of Jeanty from his stance, because holes close so much faster in the NFL, where even 300-pound defensive linemen can run impressive 40-yard-dash times.

For now, Kelly, the veteran offensive mind, has won the battle. That doesn't mean Jeanty won't try to get his stance back in the future, though.

"I'm going to try and persuade him one day. I got to earn my stripes and make some plays first, but I don't think it's going to be the end [of the stance]," Jeanty said.
