Surprise, surprise. We disagree. I think that not only will it be uncovered more, but that it'll be happening more. There's just a looser attitude today about betting.
Actually, I suspect you're probably right that gambling's more common. Almost certainly true that there's far more money bet now than 10 years ago. It's a tough comparison to make because you don't really know the baseline (hard to know with any certainty how much money moved in illegal betting markets), but access to app based gambling probably increases the number of bets made, and the percentage of people making bets.
That said, not convinced that point shaving scandals follow. I think that betting was a black market run by criminals probably increased the likelihood of point shaving scandals. In the point shaving scandals college sports has had in the past, there was basically always a member of organized crime -- usually the market maker -- approaching players with the opportunity to make easy money. That's also how it went down with the NBA Ref, if you believe his side of things.
In today's world, there's just far more transparency and visibility into betting markets and in only a few short years there have been players and coaches have been caught just making small bets. If the money moving is substantial enough to incentivize point shaving, it'll get caught pretty easily.
A somewhat related tangent: I remember in the early 1970s when the Ohio constitutional amendment was on the ballot to allow for the creation of the Ohio Lottery, there were those who said it would only shift illegal betting to legal betting (which seemed like a good idea to me), but others warned that it would increase the number of people betting (which seemed like a bad idea to me). I could not decide which was more likely, so I left that line on the ballot blank. Knowing what I know today, I would have voted against it. What I didn't comprehend at the time was that the state lottery would run all kinds of deceptive ads encouraging folks to bet. The number of people gambling today in Ohio is astronomically higher than before the lottery was created, and many of those who do so are those who can least afford it. As someone once put it, the lottery is a tax on ignorance.
Reminds me, gotta go buy a powerball ticket.
But generally, we agree about the lottery. At least in some states it funds education.
