Refs gamble, it's obvious and too easy to manipulate a close spread game.
Higgins was bad at it honestly, it's obvious he was fixing games... I don't think he hated UK , I just think in those games he was the ref that UK played in, it just happened to be money on the other side negative against UK.
A pattern appeared, he was bad at it, if there's an obvious pattern that's how you get exposed... BUT it apparently doesn't matter because nothing is ever looked into with these refs, they are all protected and cbs, espn, fox .. .they never call out the bad calls either, even in game if a call is reviewed and obviously wrong they rarely say that's wrong they just move on. Like that block review a game or two back where we all saw the review and they still called it a goal tend.
