Yeah, but the more you bet on -130/-140 money lines, the higher percentage of bets you need to win just to break even.
-110 lines? You need 52.4% to break even. You increase that? I say good luck making money in the long run. You’re just giving the house a bigger edge.
-1.5 wasn’t available for long, that thing dashed to 3.5. Ended up being the same exact result.
I’d wager whatever you’d like that after a season of taking -130+ odds, you won’t make money.
You are assuming he only bets the favorites. What if he bets the underdogs?
In reality, nothing is so simple in gambling that it can be reduced to a simple rule.
"Always bet the money line if you like the favorite and the spread is 1.5". Yuck.
"Never bet the favorite on the money line because you get paid less." Yuck, ptooey.
In truth, the only way to be a long-term winner is to make your best estimate for the outcome of the game--or even better, the range of potential outcomes--and make the bet that gives the best value. Might be the money line, might be the underdog to cover, whatever. Everything else is betting by feel or emotion.
Nothing wrong with betting by emotion, by the way. The thrill is an important part of it for many people. I love Nostical's comments above.
