College Basketball First Half Second Foul Can't Play at 20 Minutes

I've never understood arbitrary numbers so college basketball first half second foul he can't play in the first half which is up to 20 minutes. this year we've put no back in that time depending on who the player is usually a better player okay I'm just super curious about practice games minute injuries I'm super interested in that. Would we have a name yet for this thing I'd like slapping back four slapping glass slapping glass that's kind of funny I like that. When you get the Australian scientists fourth performance dude and I just sit and listen like I think like that's another thing why does everybody have to be Australian I don't understand but they'll be all scientists that understand anymore.
