John Fox impressed with rookies' enthusiasm

Denver Broncos head coach John Fox has admitted that he was impressed with his side's rookies in their first practice session.

The Broncos picked six players in the 2014 NFL Draft and added 15 players as undrafted free agents to bolster their side that lost the Super Bowl last season.

Fox told reporters: "You love getting back on the grass, no doubt about that. You spend a lot of time evaluating these guys, whether they're draft picks or college free agents.

"At this stage, after one practice, we're getting to know them and they're getting to know us. So probably a little too early to be jumping all over evaluations. But it was a good first day. I liked the enthusiasm."

Fox's side selected cornerback Bradley Roby with their first pick in the Draft.
