I like both Green Bay +3 and the Astros tonight. I was going to play Green Bay straight for 550/500. But if I add Houston to make a parley, my 550 bet will now win 1000. Can Houston lose and screw my parley. Sure, anything is possible, but I'm adding a team that is MINUS 210 for a chance to double my Green Bay winnings. Does this look as good to you as it does to me.
