If you show any sort of aptitude, they'll auto-shift the juice when you play something. Bovada are too dumb to have any real opinion about how many points Trae Young is going to score against Baylor. They get their lines from some outside dude who's only about 10% less of a moron than they are.
Have I thought about auto-shifting the juice the wrong way, and being in league with someone who would then pound the right side at optimal juice? GD right.
It is also worth reiterating that these people are complete dummies. They copy other people's work, never stick their necks out first, and just get rich off dummies. It's a great racket, but lots of dummies fall ###-first into great rackets.
