His new teammates can't stop talking about him.

Adrian Peterson blew the doors down in his debut with the Cardinals last Sunday, mowing through the Bucs for 134 yards and two touchdowns in a performance that transformed Arizona's offense.

Quarterback Carson Palmer noticed the difference right away, explaining to reporters that he could hear Peterson's feet on every play.

"He's putting so much force into the ground with every step," Palmer said, per Josh Weinfuss of ESPN. "With a cut, when he's going to sprint, he's just different.

"He's very unique. He's one of one. He runs so differently and so angry, I guess would be describing it. He runs with so much violence, every run, inside zone, outside zone."
