Yeah I think the confusion stems from the fact that they don't actually adhere to the rules. Guy's have gotten the INJ tag after one game missed, and guys have missed 3+ without getting it. Hopefully it's something Yahoo cleans up this year.
I probably wouldn't expect much from Hill either, but he's definitely worth a grab given we don't know the specifics of Gurley's injury. He could be back next week, he could be shutdown for the season.
