I can't think of any other way to make it clear, so here goes.....
Pinnacle almost always has the sharpest line due to their business model.
They have the lowest vig, so almost every sharp and insider has an account with them. If their line is off in any sport, the sharpest bettors on the planet move fast and hard. Pinny knows "whos-who" through vast experience and extensive bet-tracking. When sharps come in, Pinny adjusts their moneylines until the sharp money stops.
I was very disappointed in BetOddessa's boxing vig. I felt Joey would try to compete with Olympic and 5Dimes, giving us 4 very solid offshore boxing outs.
