Sean Payton was in the midst of making a point about something else Saturday after Day 2 of Broncos rookie minicamp when he noted one of the day’s clearest developments. Wide receiver Devaughn Vele, the seventh-round draft pick out of Utah, stood out during practice and not just because he’s 6-foot-4. “If you didn’t know, you would have said, ‘Man, Vele seems to have a pretty good rapport with Bo (Nix) today,’” Payton said. The point he set out to make was that Nix and fourth-round receiver Troy Franklin might benefit from having played together in college, but now that they’re rookies playing in a different offense, different league and with different teammates, that shared history might be, “a little overblown.” Anything can be overblown in May, but the Broncos head coach was clearly impressed by Vele, the 26-year-old rookie. “He’s got good instincts and he has really, really good ball skills,” Payton said.
