If a team is -11, I wouldn't put that in the range of expecting a blowout and a top player on the team to play less. With all the 3's taken nowadays leads can vanish so fast. You really have to destroy a team for starters to rest the last 7-10 mins of the game.
Unless you think that line is just wrong, but then in that case you should just bet the Pistons.
