As Fox talked after practice, a handful of players provided background noise as they engaged in post-practice banter in the end zone.
Fox turned and said, "They like each other."
Such camaraderie might also explain the diversion that came during the walk-through, when a small aircraft flew over the field with a message banner that read: "MEET BRONCOS AARON BREWER TONITE AT TIME SQUARE"
Brewer is Denver's low-profile, second-year long-snapper.
The plane flew over the field twice, and was reminiscent of a similar stunt that highlighted special teams captain Keith Burns when the franchise last played in a Super Bowl.
"It was a little gag," Fox said. "They have no more appearances. That was just to gag him a little bit."
Fox said that he has been pleased with his players' professionalism and focus. He said the team has not had a single case of any players breaking curfew this week.
"I couldn't ask for more, for the way they've done it," Fox said. "We've been on par. Very focused."
Still, after Friday's practice, there were still more than two days before kickoff.
With the practice work completed, Fox is hoping that players will strive for an even sharper focus.
"We talk about the mental preparation," Fox said. "They're going to continue to go through their playbooks, iPads, whatever information source they have, and continue to review. Now it's mostly just reviewing and visualizing what their job is."
To minimize distractions, the Broncos will leave their hotel where they have stayed all week — and where family and guests of players are staying — and move to another hotel on Saturday and remain sequestered overnight.
