For the record: Las Vegas had sports betting (other than horses) from the mid 1970s. The real issue is the recent mass legalisation of sports betting by many US states and the ability the gamble from your mobile phone.

Last: I never heard of Patrick Reed before your post. I Googled him. Check it out: "Reed's collegiate career was cut short following his dismissal from the University of Georgia golf team. Allegations from teammates included cheating in qualifying rounds and stealing merchandise and money from the team locker room..." What a stand up guy!
