Instead, he suggests looking at moneyline odds, whether for the favorites or underdogs, to find better opportunities.
Moneyline odds are just American odds compared to European ones or the UK, also, what are you going to do in soccer with those? Cause it's definitely not 50/50, I see no reason why he would give an advice for situations that are so specific it's harder to find them than to actually avoid playing on them

You could say taking 1.9/1.9 in tennis games is a bad idea, or is betting on any game just because of the odds.You bet for the things you might think might happen, not because of the odds, you take a 1.2 with a 4.5 in an array if you're sure of the fundamentals.
Point spread is much easier to predict than choosing match winner bet because you have a chance of still win your bet if you’re team lose when you choose + spread points.
And what value do you get for that, for example in Barcelona's upcoming game, go for the spread and you end up with 1.10.
