There are no new stories. That's common wisdom among novelists and screenwriters. Whoever first coined the saying was surely thinking of Shakespearean stories or Hollywood stories but might as well have been talking about NFL minicamp stories.
Most NFL minicamps are scheduled over the next three weeks. Those things you have been reading about over the past two weeks have been "voluntary" OTAs, which are practically the same thing, except A) the most important or disgruntled players can skip them, and B) press availability is a little more sporadic. It's a blurry distinction, but the upcoming mandatory minicamps are the last real events before teams take a few genuine days off to rest up for training camp.
