Doesn't look like it's accurate at the moment. I'm guessing the news item came after you posted and you have since seen it, but here it is anyway:
"Finally, we are introducing a new development idea: BuzzerBeta. This is an experiment on our part, introducing short, quick new features that might or might not turn out to be smart, and letting the community tell us whether they should stick around. The first of these we’re rolling out is Player Roles, where we try and indicate how players on each team have been used (not should have been used if the manager were more astute or would have been used if not injured) this season in league play. It has its flaws, and we’ll let you tell us whether you want to see more things like this. BuzzerBeta features are liable to be added, removed, replaced, or edited at any time."
