If it's a half win it's a half loss. So that's a net gain of 0.
It is always bad news to bet on teams you like. I learned that lesson a long time ago.
You need to put the money first (obviously) Since Miami is -120, you'll need to put up $120 to win $100. If you lose, you're out $120. If you win, you'll get back $220 ($120 deposit + $100 winnings)
Just to clear this up a bit, since Miami is -120 you lose $20 of "juice" if you win. So in reality a $100 bet will win u $80 not $120. So you would net a total of $180 if you were to win the bet. (Not the $220)
