Two Guardians were betting on the games they were playing in. In regards to your previous post, gambling isn't going to ruin college sports, it is in the process of ruining society. In particular, young men are ruining their futures gambling.
Since we are talking gambling, I'll throw this out there. I would bet $5,000 that in the past 3 years, at least one starting player on the football team or MBB team has bet on a game they were playing in using a gambling app. It's too easy to get away with if you do it in small numbers.
