First of all, these are not prop bets. These are standard futures bets. A prop bet is something like, "Which team will score first," or "How long with the national anthem take?" Second of all, the line is typically set to discourage action on the Cubs because they get more than enough of it already. Third of all, what trap? What in the holy hell are you talking about? 1 - Future bets are PROP bets. At any book, they fall under that category. A future bet is always categorized as a prop bet. 2 - No. The line is made to be as +EV to the book as possible. They love all the Cubs action, because the price is so off. They know every year they are going to get Cubs action so they shade the line as much as possible. You think they are making this line to discourage action? You realize that is the exact opposite of what the sports booking business is about, correct?
