Are you concerned about Stefon Diggs’ absence from the Bills’ “voluntary” Organized Team Activities? Me too. Do you find it odd that a high-character player like Von Miller has to make excuses for him? I do. After all, Miller, rehabbing from knee surgery, is present at OTAs even though he’s projected to miss the first six games of the coming season. In short, he doesn’t have to be there … but he is. Not so with Diggs.
