The kelly criterion basically states you should bet your theoretical edge over a game divided by your odds. That seems fine with over/under where your rate of return per bet is constant and near an even payoff. Does anyone have any thoughts on kelly vs moneyline? Does the methodology still apply?

For example, a 10% edge on a -150 bet: 10/-150 = -6.6%
also, a 10% edge on a +150 bet: 10/150 = +6.6%

I'm struggling here. Betting -6.6% of bankroll is impossble, and it seems only betting 6.6% of bankroll when the odds are much greater than a even money payoff (less vig) is too small an amount. What am I missing? Advice is most welcomed.
