There is legal betting on WCBB and MCBB as well just not nearly the same level of interest/scrutiny. Because there is legal gambling injuries are publicly disclosed and was in the case with Dorka.
@Monte to your point of UCONN fans wanting to know when players will return- the staff simply does not know. The staff gives us their best estimate and time frame for return but for some that does not seem to be enough. The public statement was, "Juhász is listed as day-to-day for the upcoming week" . That should be enough for even the most degenerate gambler to cast a bet.
