but why even put dallas money line on there if you just plan to hedge out of your position?
Let me break it down numbers wise.
That parlay would be $100 paying $797. Let's assume the early games cover so now the last leg is Dallas m/l. Put $50 on Eagles 1h -3 to win $35 or so.
Here's the scenarios for the above:
Cowboys go up BIG, then we have a great Eagles m/l to take +200 or so. Probably lay $200 on that to win $400. If Eagles comeback you win $400-$100 parlay - $50 eagles 1h for a gain of $250, decent return. Cowboys win you win $797-$200-$50= $547.
If its a tie at half Eagles m/l probably around -150. Put $200 on that to win $130. If Eagles win $130-$100-$50= -$20.
The plan is to try to guarantee money.
