HOUSTON -- Chargers defensive end Joey Bosa and Dallas Cowboys running back Ezekiel Elliott have pretty much been attached at the hip for years.

The two became stars at Ohio State -- leading the Buckeyes to a national championship in 2014 -- and went back-to-back in last year's NFL draft. The Chargers selected Bosa third overall and the Cowboys picked Elliott fourth overall. Bosa and Elliott lived together at Ohio State during Elliott's first two seasons in college.

And then came Saturday in Houston at the NFL Honors show. Bosa, who led all rookies in sacks last season with 10 1/2, was named The Associated Press' NFL Defensive Rookie of the Year one day ahead of Super Bowl LI. Elliott, who led the NFL with 1,631 rushing yards, was the runner-up Saturday for AP NFL Offensive Rookie of the Year to his teammate with the Cowboys, quarterback Dak Prescott. Elliott did win the FedEx Ground Player of the Year award Saturday.

Before both picked up their trophies, Bosa stopped on the red carpet before the NFL Honors show to praise Elliott.

"Living with him for a couple of years and the things that we used to do together," Bosa said, "it's just funny seeing where we are now.

"He's a superstar and I love what he's doing," Bosa continued, "and I'm really proud of him and he's going to have a lot of great years in the NFL. Everything is true what you guys think about him. He's a monster."

Elliott led the NFL in rushing as a rookie with 1,631 yards and 15 touchdowns on 322 carries and didn't even play in the regular-season finale. The last NFL rookie to lead the league in rushing yards had been Edgerrin James in 1999.

Elliott's rushing yards and touchdowns set Cowboys rookie records.

"Just seeing him take over the league like he has," Bosa said, "is unbelievable."
