With the help of an injury expert. While he also doesn't know the exact extent of Blair's injury, he provides a pretty detailed description of the situation and examples of players who enjoyed success under similar conditions in the NFL and NBA.

Since probably no team doctor or GM will be allowed to talk about why he red-flagged Blair, only time will tell how well he manages to play in the NBA.
