BOULDER -- John Elway and Kirk Cousins’ agent were in the same building at the same time.

Yet, Elway, the Broncos’ general manager, and Mike McCartney, the agent for the NFL’s most prized free-agent quarterback, never talked during the Colorado Buffaloes Pro Day at the school’s Indoor Practice Facility on Wednesday.

Didn’t shake hands. Didn’t even wave.

Apparently, McCartney and Elway were mindful of NFL tampering rules. McCartney will not talk money with teams until Monday, when the negotiating period for free agents opens. The Broncos are expected to be among the teams who will make an offer for Cousins.

With Elway and McCartney not talking to the media, CU outside linebacker Derek McCartney, who had a strong performance before 44 scouts representing 29 NFL teams, was asked if his uncle Mike told him where Cousins would play.

“I don’t know,’’ Derek McCartney said with a smile. “You’re going to have to wait and see just like me.’’

Besides Elway, the Broncos’ braintrust included head coach Vance Joseph, personnel consultant Gary Kubiak, former CU standout and director of player personnel Matt Russell and college scouting director Brian Stark.

Oh, and Trevor Siemian, the Broncos' quarterback who was there as a guest of his agent -- Mike McCartney.

The main player the Broncos' officials were interested in was CU cornerback Isaiah Oliver, who will be a first-round draft pick.

“I did have a formal meeting with them,’’ said Oliver, who had suffered a dislocated finger during the Combine gauntlet drill on Monday, yet performed all drills except the bench press and 40-yard dash here Wednesday. “Mr. Elway and everyone was in there. Coach Joseph. So, I thought it went really well. It would be an exciting place to be.’’

NFL teams work two lanes this time of year.

The Broncos used part of their day scouting future stars like Oliver. And they are also getting ready to place their bids for Cousins on Monday. Why talk now when there should be plenty of discussion Wednesday.
