Following light acclimation days last Wednesday and Thursday, the Denver Broncos officially kicked off training camp with practices on Friday and Saturday — without pads. The first four sessions were meaningful, but things will really heat up when the pads come on Monday. “Well, they all mean something,” Broncos coach Sean Payton said after Saturday’s practice. When you get into full pads, guys will play differently or step up a little differently and you get maybe a cleaner evaluation.
