The Denver Broncos just keep finding dominant young running backs. The latest, Clinton Portis, beat University of Miami teammate Jeremy Shockey for the Associated Press NFL Offensive Rookie of the Year award Tuesday.

Denver’s run on standout runners began in 1995 with Terrell Davis. It continued with Olandis Gary, Mike Anderson — the top offensive rookie in 2000 — and now Portis.

“I’m just glad to finally win something,” said Portis, who ran for 1,508 yards, by far the most among rookies and fourth overall in the NFL. “I think the last time I won anything individually was in high school. I think I was named county player of year or something like that.”

Portis earned 29 votes from a nationwide panel of sports writers and broadcasters who cover the league. Shockey, the New York Giants’ energetic and sometimes outrageous tight end, received 17 votes.

Houston quarterback David Carr and New Orleans guard LeCharles Bentley were the only other rookies receiving a vote; each got one.

Portis and Anderson are the only Denver rookies to win the award. The last four NFL Offensive Rookies of the Year were running backs: Portis, Anthony Thomas of Chicago, Anderson, and Edgerrin James of Indianapolis.
