After a pair of acclimation days on Wednesday and Thursday, the Denver Broncos kicked off the first official day of training camp on Friday with about 800 fans in attendance (capacity has been reduced due to ongoing construction at their facility). Here are five quick takeaways following Day 1 of camp as we head into the weekend.

Steinbach, 17, was decked out in a No. 10 Bo Nix jersey as a nod to Denver’s second-year quarterback. He saw Will Nelson, 17, come out of his house wearing a No. 3 Russell Wilson Broncos jersey. “I hate it,’’ Steinbach said. “It looks ugly. It will stand out a lot.”
