It feels like this article is trying to have it both ways. It claims that the Terry Rozier bet wouldn't be viable in pre-2017 because people who be savvy enough to notice the weird bet and retaliate. But in the legal market, the odd bet was noticed immediately, prop bets on Rozier were shut down before tipoff, and there was a federal investigation into it. It's a weird claim to act like the legal market enabled a successful bet that the prior illegal market would have stopped.
