Isn't it a good bet to take a 3 team moneyline parlay of teams favored by 10+ points?

Your payout would be equal to or greater than your wager and the chances of 3 teams merely winning straight up that are favored by that much are good; better than taking a single bet of one of those teams covering the spread or better than taking a moneyline wager of one of those teams winning straight up where you are goin to have to risk 5 times your payout.
