In a stacked competition among wide receivers, little-known rookie Kalif Raymond of Holy Cross raced right into sight.

Coach Gary Kubiak loudly praised Raymond during 11-on-11 drills Sunday. And during one-and-one work between wide receivers and defensive backs, Raymond juked cornerback Lorenzo Doss to separate himself by more than 10 yards for a wide-open catch.

“Kalif is very explosive,” Kubiak said.

The Broncos are looking at Raymond, who’s generously listed as 5-foot-9, as a punt returner and slot receiver, Kubiak said.

“This is my dream,” Raymond, who wasn’t drafted, said of being with the Broncos. “Anything I can do to get on the field, whether it be receiver, returner, sniper, gunner, anything they need. I’ll snap the ball if they need me to.”

With veterans Demaryius Thomas and Emmanuel Sanders set as clear leaders at wide receiver, the rest of the group is battling for jobs. They include Bennie Fowler, Jordan Taylor, Marlon Brown, Cody Latimer and Mose Frazier.

Catching attention. Durron Neal, another undrafted rookie wide receiver, beat safety Brandian Ross on a deep route up the middle for an impressive catch on a ball thrown by Paxton Lynch.

“I’ve said from Day One that wide receiver really has the chance to be the strength of our team,” Kubiak said of the group. “It’s going to be really hard to make the team at that position.”

Different tone. Offensive tackle Russell Okung, who signed a five-year, $53 million contract (with one year guaranteed) during the offseason, came to Denver from a different situation in Seattle. Training camp with the Seahawks, led by coach Pete Carroll, is more casual.

“I would say Kubiak handles things more professionally, whatever that means,” Okung said. “Pete is a lot more laid back. There’s a lot more freedom there, but I would say Kubiak is more structured and more traditional in that way. Pete’s definitely a professional, but it’s different in the sense of the discipline of what’s required of us here all of the time.”

QUARTERBACK WATCH:

A summary of how Broncos quarterbacks Mark Sanchez, Trevor Siemian and Paxton Lynch fared at practice Sunday:

Sanchez — The veteran’s timing was spot on when wide receivers worked one-on-one against cornerbacks. Sanchez routinely met them with passes that left his hand before their breaks. But in 11-on-11 work, Sanchez faded fast and lost the connection.

Siemian — Either overthrown on deep routes or underthrown on hooks, Siemian seemed lost.

Lynch — The rookie from Memphis couldn’t time receiver routes if he had a stopwatch. But in 11-on-11 work, he aired out two deep receptions that had him pumping his fist.
